Riot Blockchain Q2 earnings dented by mining revenue slump, bitcoin impairment

Riot Blockchain (NASDAQ:RIOT) stock edged down 1.2% in Tuesday premarket trading after the bitcoin (BTC-USD) miner saw a decline in mining revenue as well as a sizable non-cash BTC impairment. Adjusted EPS of -$0.50 at the end of June missed the average analyst estimate of -$0.15 and dropped from three cents at June 30, 2021. Revenue of $72.9M at June 30 fell also short of the $72.6M consensus but rose from $34.3M in the year-ago quarter. Q2 mining revenue increased to $46.2M from $31.5M in Q2 2021, driven by an increase in the number of bitcoins (BTC-USD) mined, which was negatively impacted by lower BTC values in Q2 vs. Q2 2021.Adjusted EBITDA for Q2 was -$65.2M compared with $2.39M a year before. The company produced 1,395 bitcoins (BTC-USD) during the second quarter, up from 675 BTC in Q2 of last year.
