The latest financial report for the fourth quarter of the 2026 fiscal year released by IREN lays out the transformation progress of this traditional Bitcoin mining company alongside the pressures of reality: total quarterly revenue of approximately $137.2 million, but adjusted EBITDA of only about $19.2 million, about 53% lower than market expectations. Following the release of the financial report, the company's stock price quickly fell in after-hours trading, with a decline of over 8%. The most striking aspect is the clear reversal in revenue structure—this quarter, AI cloud service revenue was approximately $70.5 million, nearly doubling from about $33.6 million in the previous quarter, and for the first time, it surpassed Bitcoin mining revenue; meanwhile, mining business revenue plummeted from approximately $111–111.2 million in the previous quarter to about $66.7 million, as the weight within the total revenue was significantly squeezed by AI cloud computing power and the neocloud business. This set of data clearly shows that IREN’s strategy of transforming from a Bitcoin mining company to AI-focused cloud and computing services is being rapidly implemented, with new revenue engines beginning to take over the company's growth narrative, but profitability and cash returns have not kept pace, as the cost structure and investment rhythm continue to suppress profit performance. At this point in time, the market does not buy into the combination of "the revenue focus shifting to AI cloud while profitability is significantly below expectations"; the decline in after-hours stock price reflects that investors are adjusting their short-term pricing and tolerance for this transformation path.

AI Cloud Soars: Revenue Doubles, First to Surpass Mining

Specifically for this quarter's data, IREN's neocloud and AI cloud services have jumped from being "marginal businesses" to the core of revenue. The financial report shows that AI cloud service revenue increased from approximately $33.6 million in the previous quarter to about $70.5 million in one quarter, nearly doubling, and accounting for over half of the total revenue of $137.2 million. This is not a gentle climb, but rather a leap in magnitude: while Bitcoin mining revenue fell from approximately $111–111.2 million to about $66.7 million, the AI cloud business has almost single-handedly supported the overall revenue "facade" of the company.

More critically is the structural inflection point—this is the first time IREN has realized AI cloud revenue surpassing Bitcoin mining revenue in a single quarter, marking a symbolic moment where the revenue composition shifted from "mining-led" to "AI cloud-led." For the capital market, "mining companies transitioning to AI computing power" has often remained at the level of storytelling, and this financial report is the first to provide quantifiable verification: the traditional mining segment is yielding its revenue C position, while neocloud and AI cloud services have become the main drivers of the growth curve. At the industry level, mining companies like Core Scientific and Hut 8 are also laying out AI-oriented computing and cloud services, making IREN's structural flip appear more as part of a sector-wide trend rather than an isolated event. Over the next few quarters, whether AI cloud revenue can maintain high growth while improving profitability will become a key data coordinate to assess the feasibility of this transformation path.

Mining Revenue Plummets: Traditional Core Business Gives Way

Alongside the surge in AI cloud revenue is the obvious "collapse" of Bitcoin mining revenue. In the latest quarter, IREN's Bitcoin mining revenue was only about $66.7 million, nearly halving compared to approximately $111–111.2 million in the previous quarter, with total revenue at about $137.2 million, indicating that the traditional mining business's share in the company's revenue has fallen to less than half. More critically, the mining segment is no longer the first source of revenue; AI cloud services with about $70.5 million have overtaken mining, directly rewriting the longstanding financial narrative of this mining company that "mining is the main business."

From a cash flow perspective, the decline in mining revenue has weakened IREN's ability to self-fund through on-chain output, and the stability of short-term operating cash flow now relies more on contracted computing power leasing and AI cloud service orders. In an industry landscape characterized by Bitcoin price fluctuations, rising overall computing power, and high power and infrastructure costs, mining companies' traditional model of earning returns solely from mining faces common challenges of revenue volatility and cost pressures. Many leading players have begun to shift some of their computing power from single mining to leasing for AI and high-performance computing clients. The significant decrease in the weight of IREN's mining revenue this quarter is a direct manifestation of this sector-level shift in the financial report, where the core question in the coming quarters is no longer "how many coins can be mined," but rather "can computing power services replace mining to continuously generate predictable cash flow for shareholders?".

EBITDA Halved from Expectations: Growth Story Meets Profitability Test

In the structural transition of computing power from mining to AI cloud, IREN's adjusted EBITDA for this quarter was only about $19.2 million, which was approximately 53% lower than market expectations, becoming the direct pressure point for the stock price falling over 8% after the financial report was published. Total revenue has risen to about $137.2 million, but the results show that the shift in revenue focus to AI cloud has not concurrently translated to stronger cash creation capabilities, with overall profit margins significantly below the optimistic pricing of the capital market for the "growth + transformation" combination, and cost control has not shown improvements in efficiency matching the business restructuring.

For investors, this set of data pulls the valuation discussion from "how much multiple can AI cloud high growth give" back to the reality game of "is the profitability base overestimated": on one side is the growth story with AI cloud revenue doubling quarter-over-quarter and surpassing mining business; on the other side is the EBITDA far below expectations, with short-term profitability under pressure in cash flow arithmetic. More critically, within the current information scope, the management has not provided a clear path and timeline for profitability improvement, leaving the market to adjust its assumptions about future quarters' profit margins and capital expenditure intensity based on this quarter’s gap, naturally narrowing the premium space, increasing risk compensation demands, and shifting short-term trading logic to "first observe profit recovery, then talk about growth premium."

Mining Companies Collectively Bet on AI Computing Power: Where Does IREN Stand?

Horizontally comparing with peers, mining companies like Core Scientific and Hut 8 are also strengthening the "computing power services" and "AI-oriented infrastructure" labels in public information, but many still use mining as the cash flow base, while incrementally adding AI computing power on the margins. IREN, however, has directly written transformation into its revenue structure: in the latest quarter, AI cloud service revenue of about $70.5 million has doubled quarter-over-quarter and for the first time surpassed around $66.7 million in mining revenue, making it a radical example in the industry where "computing power services > mining." This speed of change allows IREN to stand closer to the front in the narrative queue of "mining companies transitioning to AI cloud," gaining an early advantage with the premium story of "revenue structure has been reshaped," while also exposing the shortfall that its profitability model has yet to align.

The capital market has started to distinguish between single mining companies and those transitioning to AI cloud and computing services: the former resemble cyclical assets following price and overall computing power fluctuations, while the latter attempt to align with "infrastructure + cloud service" type valuations. However, with IREN's adjusted EBITDA this quarter at only about $19.2 million and approximately 53% lower than expectations, and the stock price falling over 8% after the financial report was released, it indicates that before the market applies a new multiple on "AI cloud revenue doubling," it will first discount based on profitability, capital expenditure intensity, and execution rhythm. For IREN, the true pricing inflection point does not lie in whether AI cloud revenue can continue to lead over mining, but rather whether it can prove over the next few quarters that this new structure has sustainable profitability and identifiable cash flow quality.

After an 8% Drop in Share Price: How Long is the Market's Patience for IREN?

A drop of over 8% after hours has already provided the core evaluation of this financial report: the capital market recognizes the "directionally correct" signal of AI cloud revenue doubling quarter-over-quarter and for the first time surpassing mining revenue of about $66.7 million, but quickly reflects a "failure" in results with an adjusted EBITDA of only about $19.2 million and 53% lower than expected in valuation. In the short term, the focus of investors' reassessment is no longer just on computing power and revenue scale, but three clues: first, whether AI cloud business can significantly increase overall gross profit and EBITDA contribution while maintaining rapid growth in the next few quarters; second, whether traditional Bitcoin mining revenue can find a more stable cash flow base after falling from approximately $111–111.2 million in the previous quarter to about $66.7 million, under the sector cycle and company strategy; and third, in the absence of clear guidance for the next quarter and more detailed commentary from management, how quickly the capital expenditure rhythm, cost control efficiency, and free cash flow paths will become predictable. As of August 28, 2026, IREN's valuation narrative is transitioning from the "possibility of successful transformation" to "evidence of transformative profitability," with the fluctuations in AI cloud revenue, mining business, and EBITDA repair over the coming quarters jointly determining how much patience the market is willing to reserve for this mining company's new story.
