Monadelphous (ASX:MND) Wins A$120m in Contracts and Is Up 72%: Is It Still a Buy?

 Monadelphous Wins A$120m in New Contracts

Monadelphous Group (ASX: MND) has quietly become one of the ASX’s standout industrial performers, with the stock up around 72% over the past 12 months while the broader market rose just 3%. The latest lift came this week, when the engineering services group announced roughly A$120 million in new mining and renewable energy contracts, nudging shares up about 2% to around A$30. But for anyone eyeing the stock now, the harder question is this: after a run this strong, does another contract win still make Monadelphous a buy, or is the value already gone?

What are the Best ASX Stocks to invest in right now?

Monadelphous Deepens Its Grip on the Resources Boom

The A$120 million haul isn’t one big project. It’s a spread of work that shows why Monadelphous keeps winning: a five-year mobile crane and lifting services deal with Rio Tinto, a three-year maintenance panel with Port Waratah Coal Services in Newcastle, and a battery energy storage system (BESS) build for Fortescue, the company’s third BESS project for that miner.

The key point is that Monadelphous sits in a sweet spot. It doesn’t dig the ore or carry commodity-price risk directly. Instead, it builds and maintains the infrastructure that miners depend on. As long as Rio and Fortescue keep spending, Monadelphous keeps earning, which gives it lower-risk exposure to the mining cycle than the miners themselves.

The maintenance side is the quiet strength. Those contracts run for years and produce steady, repeat revenue, far more predictable than one-off construction jobs. This win also follows roughly A$145 million in contracts in April and A$110 million in January, part of a record run of work, and the BESS project plugs the company into mining’s long-term decarbonisation push.

The Catch: Has the 72% Run Priced In the Good News?

Here’s the problem. A great business isn’t the same as a great buy. Price matters. After a 72% climb, Monadelphous trades at around 25 times forecast earnings, a premium rating for an engineering and services company.

That premium isn’t unjustified, because the company is growing quickly. First-half FY26 revenue jumped 45.6% to a record A$1.53 billion, and net profit rose 52.6%. Measured against last financial year’s earnings, the multiple looks steeper still, which is the market’s way of saying it expects this fast growth to continue. That leaves little room for disappointment.

The risk for new buyers is simple: wins of this size are now expected. The market already assumes Monadelphous will keep landing work, so an A$120 million announcement, while welcome, doesn’t shift the investment case much. In our view, the good news may already be in the price. If miner spending slows or tight labour costs squeeze margins, an expensive stock has further to fall.

The Investor’s Takeaway for MND

For investors who already hold Monadelphous, there’s little reason to head for the exit. The fully franked dividend, steady maintenance revenue and a record order book all support holding the stock through the cycle.

For new buyers, discipline may be the smarter call. Buying a quality company straight after a 72% run rarely offers an attractive entry point, and a market pullback could provide a better one. The things to watch from here are the size of the order book, profit margins, and capital spending guidance from big miners like Rio Tinto and Fortescue, because their budgets ultimately drive Monadelphous’s revenue.
