Bitcoin mining company Marathon Digital Holdings announced its second quarter financial results, revealing a revenue of $145.1 million, which was lower than the expected $157.9 million. The company attributed the decline in sales mainly to operational difficulties and the recent bitcoin halving event. Additionally, Marathon Digital's adjusted EBITDA turned from $35.8 million in the previous year to a loss of $85.1 million in the second quarter, mainly due to the change in the fair value of its digital assets and a decrease in the number of BTC mined during the quarter. Despite these challenges, Marathon Digital currently holds over 20,000 BTC on its balance sheet. Its stock price dropped approximately 8% after Thursday's closing hours, trading at around $18.14.
