Rhea-AI Summary

Boost Run Inc. (BRUN) reports explosive top-line growth but a large loss for the quarter and year-to-date as it scales its GPU infrastructure business and completes its SPAC merger with Willow Lane Acquisition Corp. For the three months ended June 30, 2026, revenue was $31.1 million, up sharply from $8.4 million a year earlier, driven mainly by GPU lease income. For the six months, revenue rose to $42.1 million from $12.6 million.

Despite this, Boost Run posted a quarterly net loss of $75.0 million and a six‑month net loss of $79.2 million, compared with modest profits in 2025, largely due to much higher depreciation, lease costs, interest, and a $55.7 million income tax provision tied to its change in tax status after the business combination. Operating cash flow was strong at $114.2 million for the first half, supported by large customer deposits of $128.4 million (current and non‑current) and non‑cash charges.

At June 30, 2026, Boost Run held $120.2 million of cash and $13.0 million of restricted cash, versus $9.7 million cash at year‑end 2025, after raising approximately $114.1 million of net SPAC proceeds and $43.4 million from warrant exercises. Total assets were $742.3 million, with large operating and finance lease right‑of‑use assets, and total liabilities were $642.2 million, including $238.1 million of finance lease liabilities and $78.5 million of other financial obligations from a new $100.0 million software licensing and support arrangement.
