Shares of bitcoin miner Marathon Digital (NASDAQ:MARA) advanced 7% in Tuesday afternoon trading despite Cowen analyst Stephen Glogola maintaining his Market Perform rating and reducing his full-year revenue and adjusted EBITDA estimates. The downbeat coverage comes as Marathon (MARA) remains exposed to execution risk on it ability to reach its targeted 23.3 exahash per second of mining capacity given reliance on third-party suppliers and a lack of infrastructure control, Glogola wrote in a note to clients. Specifically, Glogola lowered his 2022 revenue estimate to $150M from $204M, compared with the consensus of $186.2M. For adjusted EBITDA, the analyst sees Marathon (MARA) turning in $39M vs. $86M in the previous estimate following a weaker-than-expected second quarter due to a slew of inactive miners resulting from storms and energization delays. Perhaps bitcoin's (BTC-USD) intraday gains are supporting Marathon's (MARA) upswing. The crypto rose 2.7% to $21.57K at around 2:45 p.m. ET. For a contrarian view, SA contributor Investor Tip likes Marathon Digital as a Buy during the ongoing market downturn. At the beginning of August, Marathon Digital expands credit facilities with Silvergate to boost funding options.
