This is inaccurate. @MARA did not purchase any additional bitcoin. We received it back from a loan.

Is Morgan Stanley getting incrementally more positive on @MARA? "We recently had the opportunity to interview MARA CEO and Executive Chairman Fred Thiel, and we were encouraged by Fred's bullishness on the potential to sign two HPC data center transactions before year-end . . . the feedback that the AI industry has a heightened sense of urgency to secure power, plus MARA management commentary, implies that we could be wrong in our conservatism."

This news doesn't affect @MARA's recently acquired Matagorda County site. It actually makes incumbent loads and East/SE Texas sites (like the strategically located powered site in Matagorda County) more valuable. It impacts the ability to grow West Texas sites. kcentv.com/article/news/loca…

Thanks @matthew_sigel, glad to see someone reading the fine print 😀
$MARA interesting footnote in the presentation: Milestone payment 1 is not due on purchase of Matagorda site unless site is approved in Batch Zero by ERCOT. Good job w/ that one team.

An important step in expanding MARA's long-term development pipeline. This is a multi-year, milestone-based project, and we'll share more as we reach key development and regulatory milestones.
MARA has entered into a definitive agreement with HIF to acquire a strategic powered land site in Texas. The site spans more than 1,200 acres with access to up to an initial 1 GW of grid capacity by October 2027 and up to 2 GW by April 2028, subject to ERCOT approval. We intend to develop it as a large-scale digital infrastructure campus supporting high-performance computing, with flexible compute including Bitcoin mining. This expands our capacity pipeline and our long-term investment in Texas. Learn more: ir.mara.com/news-events/pres…

Seeing some questions about Morgan Stanley's updated @MARA price target. The main driver is straightforward: the decline in BTC price at the end of 2Q. One thing worth noting: the report states $MARA "still holds approximately 54,000 BTC." That's not accurate. As of the end of 1Q26, we held approximately 35,000 BTC. The report also acknowledges the potential upside from our Starwood JV discussions: "We acknowledge the risk to our PT in the form of the Starwood JV... Should a deal manifest, our valuation of $MARA as a Bitcoin mining company would be rendered outdated and would not properly value $MARA as a player in the HPC trade." In other words, their current valuation reflects $MARA as a bitcoin mining company because no HPC deal has been announced. If that changes, they acknowledge their valuation framework would need to change as well.
