SEC filingIREN's MD&A highlights a swing to $86.9M net income in FY2025 driven by a 168% surge in Bitcoin mining revenue and a $77.5M non-cash gain on financial instruments.
IREN Limited describes itself as a leading owner and operator of next-generation data centers powered by 100% renewable energy (whether from clean or renewable energy sources or through the purchase of RECs). Its data centers are purpose-built for power dense computing applications and currently support a combination of GPUs for HPC and AI services and ASICs for Bitcoin mining. The company has been mining Bitcoin since 2019 and typically liquidates all Bitcoin mined daily, holding no Bitcoin on its balance sheet as of June 30, 2025. IREN is also pursuing a strategy of expanding into HPC and AI services, including AI Cloud Services launched in 2024.
The Business section describes two primary revenue-generating activities: Bitcoin mining and HPC/AI services. Bitcoin mining generates revenue by earning Bitcoin through block rewards and transaction fees from operating ASICs, which are then exchanged for fiat currencies such as USD or CAD. HPC and AI services include AI Cloud Services that provide cloud-based GPU computing to customers for AI training and inference workloads, and potentially Colocation Services. No revenue share percentages are disclosed for these segments.
IREN's Bitcoin mining operations use ASICs (Bitcoin miners). For AI Cloud Services, as of June 30, 2025, IREN had approximately 1.9k NVIDIA H100 and H200 GPUs deployed at its Prince George site. Subsequent to June 30, 2025, IREN procured approximately 5.5k NVIDIA B200 GPUs, 2.3k NVIDIA B300 GPUs, and 1.2k NVIDIA GB300 GPUs, bringing the total GPU fleet to approximately 10.9k NVIDIA GPUs. IREN is also developing "Horizon 1," a direct-to-chip liquid cooling deployment at its Childress site with up to 50MW IT load, targeting energization by end of calendar year 2025.
For Bitcoin mining, IREN contributes hashrate to global mining pools, currently using Antpool and Foundry as main providers. Bitcoin mined is transferred daily to Kraken, a U.S.-based digital asset trading platform, and exchanged for fiat currency. IREN has onboarded Coinbase as an alternative platform but has not utilized it as of June 30, 2025. For AI Cloud Services, IREN markets and sells computing power directly to customers, with contract terms ranging from on-demand to 3 years, including white-labelled compute with leading US AI cloud providers. No single customer concentration is disclosed.
In Bitcoin mining, IREN competes with public companies such as Bitdeer Technologies Group, Bitfarms Ltd., Cipher Mining Inc., CleanSpark, Inc., Core Scientific Inc., Hut 8 Corp., MARA Holdings, Inc., Riot Platforms, Inc., and TeraWulf Inc. In HPC and AI services, competitors include AI Cloud providers like Amazon Web Services, CoreWeave, Crusoe Cloud, Google Cloud, Lambda Inc., Microsoft Azure, Nebius, and Oracle Cloud, as well as Colocation providers like Digital Realty, QTS, CyrusOne, Equinix, Vantage Data Centers, and Aligned Data Centers. The filing notes that other Bitcoin and digital asset mining companies may also diversify into HPC and AI services.
IREN's growth strategies include: (1) expanding and diversifying revenue streams into HPC and AI services, including through AI Cloud Services and potential Colocation Services; (2) adding new sites with attractive energy arrangements; (3) considering Bitcoin mining expansion opportunities, though a pause was announced after reaching 50 EH/s; (4) potentially owning, developing, and operating renewable generation and energy storage; and (5) considering strategic acquisitions and other value-enhancing opportunities.
As of June 30, 2025, IREN employed 257 employees in the United States, Canada, and Australia, and engaged approximately 200 contractors and sub-contractors at its US sites. None of its employees are represented by labor unions. The company reports that 23% of its workforce are women, and 21% of leadership positions are filled by women, including key roles such as Chief Legal Officer, Chief Financial Officer, Site Manager, and Operations Manager.
IREN Limited delivered a transformative fiscal year 2025, reporting total revenue of $501.0 million, a 168% increase from $187.2 million in the prior year. This top-line growth was overwhelmingly driven by the core Bitcoin Mining segment, which generated $484.6 million in revenue, up from $184.1 million. The $300.5 million increase was attributed to a $185.3 million uplift from higher average Bitcoin prices and a $115.2 million contribution from a significant expansion in operating hashrate, which averaged 25.7 EH/s compared to 6.6 EH/s in FY2024. The nascent AI Cloud Services segment also contributed $16.4 million, up from $3.1 million, following its operational launch in February 2024.
The company achieved a net income of $86.9 million, a dramatic swing from a net loss of $28.9 million in FY2024. This profitability was heavily influenced by a $77.5 million non-cash unrealized gain on financial instruments, primarily related to the Capped Call and Prepaid Forward Transactions entered into alongside convertible notes issuances. This gain was partially offset by a $20.0 million loss contingency for a legal settlement and a $7.2 million impairment charge for miners held for sale. On an operational basis, Adjusted EBITDA, a key management metric, surged 395% to $269.7 million, with the Adjusted EBITDA margin expanding from 29% to 54%. This margin improvement occurred despite a significant increase in the net electricity cost per Bitcoin mined, which rose to $25,642 from $18,127, driven by the April 2024 halving event and increased global hashrate.
The business is characterized by a dominant Bitcoin Mining segment and an emerging AI Cloud Services segment. Bitcoin Mining's revenue growth was fueled by both price and volume, with the number of Bitcoin mined increasing to 5,499 from 4,191. However, the cost of revenue for this segment nearly doubled to $157.7 million, primarily due to higher electricity charges and employee benefits to support the expanded hashrate. The AI Cloud Services segment, while small, demonstrated rapid growth and represents a strategic diversification effort. Its cost of revenue was $1.3 million. The company's overall operating expenses saw a significant increase, with selling, general and administrative expenses rising to $136.5 million from $70.4 million, driven by higher stock-based compensation, professional fees, and costs associated with scaling operations, including the purchase of renewable energy certificates (RECs). Depreciation and amortization also surged to $181.1 million from $50.5 million, reflecting the massive investment in mining and HPC hardware and data center infrastructure.
Management's outlook is focused on aggressive expansion and diversification. In Bitcoin mining, the company is developing two massive sites in Sweetwater, Texas, totaling 2,000MW, with grid connection and substation energization targeted for Q2 CY2026 and Q4 CY2027. A key strategic priority is the expansion into HPC and AI services. The company plans to grow its GPU fleet to approximately 10.9k NVIDIA GPUs by the end of calendar year 2025, including next-generation B200, B300, and GB300 chips, to be installed at its Prince George site. This is supported by a 50MW direct-to-chip liquid cooling deployment at the Childress site, targeting energization by the end of CY2025. Management believes its existing cash of $564.5 million, cash flows from operations, and financing activities are sufficient to meet liquidity needs for the next 12 months. This outlook is underpinned by $701.2 million in net proceeds from convertible notes and $601.8 million from at-the-market equity sales during FY2025, providing a robust capital base for its ambitious growth plans.
As of June 30, 2025, IREN held $564.5M in cash and cash equivalents, up from $404.6M a year earlier. Total assets were $2.94B, driven by $1.93B in property, plant and equipment (net) and $211.6M in financial assets (prepaid forward contracts). Total debt stood at $962.8M, consisting of $427.8M in 3.25% convertible senior notes due 2030 and $534.9M in 3.50% convertible senior notes due 2029. Shareholders' equity was $1.82B, with retained deficit of $(596.2)M. The company also held $127.9M in derivative assets (capped calls and Bitcoin purchase option).
Accounts payable and accrued expenses included $79.7M for mining hardware from Bitmain. The company had $20.0M in loss contingencies related to a settlement with NYDIG. Non-cancelable operating lease obligations totaled $1.8M undiscounted. No other material purchase commitments were disclosed.
IREN did not repurchase shares or pay dividends. The company issued $990M in convertible notes (net proceeds $704M after costs and capped call/prepaid forward transactions). Capital expenditures (payments for property, plant and equipment and hardware prepayments) totaled $1.37B, representing 274% of revenue. The company also entered into prepaid forward contracts for 14.5M shares and capped call transactions to reduce dilution.
IREN operates as a single operating segment. Revenue is disaggregated by geography: Australia (Bitcoin mining) $484.6M, Canada (AI Cloud Services) $16.4M. Long-lived assets are located in the US ($1.63B), Canada ($337.2M), and Australia ($1.7M).
Risk Factors detail evolving US tariffs (10% baseline plus proposed 100% on semiconductors) and disputes over origin of imports from Indonesia, Thailand and Malaysia that could trigger up to $100M in additional duties. BC Hydro's extended suspension on new crypto connections and Texas SB 6 large-load interconnection rules add regulatory uncertainty and potential cost increases.
Heavy dependence on Bitmain for ASICs and limited GPU suppliers creates procurement risk amid global chip shortages and long lead times (15-113 weeks for circuit breakers). Hardware obsolescence, serial defects, and supply-chain disruptions from weather, freight bottlenecks or China-related policy shifts are explicitly flagged.
Rapid shift toward HPC and AI services introduces new competition, pricing pressure, customer-acquisition challenges and possible displacement of Bitcoin mining capacity. Limited prior experience and need for data-center retrofits heighten execution risk.
$990M in convertible senior notes plus equipment leases expose the company to dilution, covenant restrictions and default risk if cash flows from mining or HPC contracts prove insufficient. Ongoing capital needs for site development and hardware replacement are emphasized.
Bitcoin price volatility (FY2025 range $53,948-$110,000), potential proof-of-stake transition, and fluctuating transaction fees directly affect revenue. Internet outages, mining-pool dependency and custom-firmware adoption risks are also disclosed.
