For IREN shareholders, the loss over the past year was 65.6%, including dividends. If you had bought in on 10 November 2025, you were effectively backing two stories at once. One was the September 2024 bull case built on 40% revenue growth, a 24% profit margin and a 60x future P/E over five years. The other was a later, more aggressive AI cloud pitch. Which of those specific assumptions failed to account for what actually unfolded?

This theme extends beyond IREN. See which of 53 AI infrastructure stocks may still merit a closer look.

The Argument You Would Have Been Weighing Up On IREN

The shares cost US$60.17 at the start, and anyone buying IREN was choosing between two very different but plausible stories about the same business.

On the upside, the September 2024 narrative from User floated a Fair Value of US$72.52 as a price implied by 40.0% revenue growth, a 24.0% profit margin and a 60.0x future P/E over a 5 year horizon built on efficient renewable powered Bitcoin mining plus early AI exposure.

The later October 2025 bear case sketched a Fair Value of US$29.55 as a model driven by 45.6% assumed revenue growth and a 52.7% profit margin, while warning that rapid AI cloud and data center expansion funded with heavy debt could strain cash flows and increase risk.

What The Evidence Did To The IREN Argument

IREN went all in on AI infrastructure, signing multi year GPU cloud deals with Microsoft, NVIDIA and others, securing over US$4b of contracted AI cloud ARR and billions of mostly prepaid or asset backed financing. That flow of contracts and funding clearly backed the bull story on capacity growth and customer demand, and it also validated the pivot away from Bitcoin mining.

The hard numbers pulled the other way. Reported revenue fell from US$240m in Q1 2026 to US$228m in Q1 2027, and net income swung from a US$385m profit to a US$263m loss, so the high margin profitability assumption remained unproven. The evidence cut both ways.

What You Would Be Paying For In IREN Today

Today IREN trades at US$19.73, well below the starting point of this story, while the current Narrative’s Fair Value sits above that share price according to BlackGoat, a Simply Wall St Community investor who wrote the Narrative.

The pitch now centers on IREN as an AI infrastructure and energy efficiency play rather than just a Bitcoin miner. For that higher figure to be justified at any point, a buyer today would need the AI and high performance computing operations to mature into a sizeable, commercially resilient revenue stream.

"Over the past year, that "PR effort" proved to be the single most important, high-conviction part of the thesis. I watched IREN's management execute relentlessly, moving light-years ahead of its mining competitors."

Where IREN’s Power Demand Leads

IREN leans on energy hungry data centers and high density computing. Your focus goes to chips and cooling first, but dependable electricity comes before both.

Elsewhere in this story, another operator studies that constraint. It designs hardware that helps generate and move large amounts of power to industrial users.

Its real leverage lies in the long relationships after each installation. Once hardware is deployed, years of servicing and upgrades can follow.

As AI infrastructure spreads, these recurring support ties may grow more important. You can study the power behind IREN’s customers, not just the computing.
