SYDNEY, Australia, May 11, 2022 (GLOBE NEWSWIRE) -- Iris Energy Limited (NASDAQ:IREN) ("Iris Energy" or "the Company"), a leading sustainable Bitcoin miner which is building an institutional-grade infrastructure platform with 15 EH/s of operating and contracted miners (10 EH/s expected to be operational by early 2023), today reported its financial results for the third quarter ended March 31, 2022. All $ amounts are in United States Dollars ("USD") and all A$ amounts are in Australian Dollars ("AUD"), unless otherwise stated.

"We remain focused on delivering our strategy of building a global institutional-grade data center platform for our shareholders," stated Daniel Roberts, Co-Chief Executive Officer and Co-Founder of Iris Energy. "We expect the next 12 months will be transformational for the Company."

Iris Energy's President, Lindsay Ward, commented, "Over the quarter, the Iris Energy team continued to expand and safely build out our second and third proprietary data center sites in British Columbia, Canada with our fourth site in Texas breaking ground in April. The next 12 months will be an exciting period for the Company as we deliver our hashrate growth targets."

Third Quarter FY22 Results

Iris Energy generated quarterly revenue of $15.2 million (A$20.2 million) vs. $2.8 million (A$3.7 million) in the prior-year quarter, Adjusted EBITDA of $7.3 million (A$9.8 million) vs. $1.6 million (A$2.1 million) in the prior-year quarter and Adjusted EBITDA Margin of 48% vs. 57% in the prior-year quarter. The increases in revenue and Adjusted EBITDA are largely attributable to the Company's increased hashrate and Bitcoin mined from the installation of additional capacity at Canal Flats.

Adjusted EBITDA Margin was lower than the prior-year quarter predominantly due to increased corporate costs following the IPO as well as expenses to support the Company's expansion to 15 EH/s of contracted miners and our development pipeline in excess of 1GW.

IFRS Net Loss After Tax for the quarter was $2.7 million (A$3.6 million), compared to a Net Profit After Tax of $0.5 million (A$0.7 million) in the prior-year quarter, driven predominately by unrealized foreign exchange losses of $5.8 million (A$7.8 million).

Iris Energy generated positive cash flow from operations during the quarter of $4.6 million (A$6.1 million). Iris Energy's total assets increased 13% in the quarter to $557.3 million (A$743.2 million).

Operational and Corporate Highlights

600MW connection agreement signed with AEP Texas at the Company's Childress site (Texas, USA), increasing the Company's total announced power capacity to 795MW
Expansion to 15 EH/s of installed capacity progressed well across four data center sites:

- Mackenzie (BC, Canada) – first 0.3 EH/s (9MW) was commissioned ahead of schedule following quarter end on April 12, with remainder of the first 1.5 EH/s (50MW) still on track for Q3 CY22.

- Prince George (BC, Canada) – first 1.4 EH/s (50MW) remains on track to be energized by the end of Q3 CY22, with foundation works for the first data center building completed ahead of schedule and ongoing site grading, civil works and foundation works progressing for the full 2.4 EH/s (85MW) build out, with the additional 1.0 EH/s (35MW) anticipated to come online in CY23

Operating and Financial Overview

The Group uses EBITDA and Adjusted EBITDA as a metric that is useful for assessing its operating performance before the impact of non-cash and other items.

EBITDA is net profit or (loss) from operations, as reported in profit and loss, before finance income and expense, tax and depreciation and amortization.

Adjusted EBITDA is EBITDA adjusted for removing certain non-cash and other items, including share-based payment expenses, foreign currency gains/(losses) and one-time transactions. The below table reconciles (Adjusted) EBITDA to Net Profit/Loss After Tax.
