Company overview

Company snapshot

Its vertically integrated approach positions it competitively within the capital markets and digital infrastructure sectors.

Foolish take

Iren Limited stock has gone parabolic this year. Its profitable Bitcoin mining operations have helped fund a transition to focusing on offering hyperscalers and other artificial intelligence (AI) companies compute power. Discovery Capital may have sensed a bubble in AI stocks, deciding to take some profits.

The firm also sold its entire stake in Iren peer Nebius Group in Q3. That position was valued at over $200 million as of Sept. 30. Both Nebius and Iren are considered neocloud companies, offering existing data center space to tech giants, smaller developers, and others needing compute power for AI model training and inference.

Iren has raised multiple rounds of capital this year. That increasing debt load might be what Discovery managers saw as a red flag for future stock returns. Iren's most recent offering was for $2.3 billion in convertible senior notes closed on Dec. 8.

Mounting debt isn't necessarily a red flag as the money is being invested to increase capacity for existing customer agreements. Investors are beginning to fear that those contracts may not pan out if the AI bubble pops and demand tanks, however.

Taking profits after a parabolic run isn't a bad idea, and Discovery Capital still maintains a meaningful position in Iren. Investors should take note that one can reduce risk and lock in profits while not necessarily exiting a position. Buying or selling in thirds is one technique for risk mitigation.
