What Is Solaris Getting For All That Spending?

For questions about this article or underlying research, email help@trefis.com.

Solaris Energy Infrastructure (SEI) has been buying turbines and other power equipment for its Power Solutions business. The company spent about $1.15 billion on buildings and equipment over the twelve months to June 2026. Three years earlier, the same twelve-month bill was $89.2 million. So what share of its sales do you think Solaris now spends on that equipment?

How Big Is Solaris’s Spending Bill?

Solaris spent the equivalent of 151% of its sales over the twelve months to June 2026. That was more than it took in from customers. Three years earlier, the share was 26.5%. The bill is about 12.9 times what it was then, and it is still growing. During the quarter to June 2026, spending was 166% higher than in the same quarter a year earlier.

Can Solaris Pay For It?

Solaris spent more than its business brought in during the quarter to June 2026. The bill came to 264% of the cash its operations produced, compared with 766% in the same quarter a year earlier.

That 264% share is lower than a year ago, yet the cash left after the spending fell nearly twice as far below zero as a year earlier. It was below zero in three of the last four quarters. Put plainly, the business is not paying for its own bill.

Solaris has money to fill the gap for now. The company held $824 million in cash and short-term investments at the end of June 2026, against $2.5 billion of debt. Management said on its fiscal Q2 2026 call that projected growth is supported by its operating cash and its liquidity: more than $800 million of cash plus an unused $650 million credit line. In September, the company also announced a plan to sell more notes, partly to pay for growth spending.

What Has The Spending Bought So Far?

Sales at Solaris over the twelve months to June 2026 were 127% higher than three years earlier.

Solaris spent about $1.7 billion on equipment over the last three years. The cash its business brings in each year is now $335 million higher than three years ago. At that pace, the extra cash would take about five years to equal what was spent, and not all of that growth came from the spending. The business has grown fast, but its cash has not caught up with the bill.

What Must Go Right For Solaris

Management points to its contracts. On the fiscal Q2 2026 call, management said 2.3 gigawatts of capacity is under long-term contract and has “a clear path to significant free cash flow” over the next decade, adding that existing customers are choosing to expand their contracts. Management tied its outlook for the fourth quarter of 2026 to power coming on at its Stateline joint venture and at the first site for a third hyperscaler customer.

The figure to watch is the cash Solaris has left after its spending each quarter. That cash fell further below zero in the quarter to June 2026 than a year earlier. The next report is expected on or around November 4, 2026.

How To Act On SEI?

Not necessarily on Solaris Energy Infrastructure alone, if your goal is long-term wealth. Wealth is built by owning the companies that keep outperforming, the leaders of their industries, wherever they are. Solaris Energy Infrastructure is one. Over the five years to October 2026, its stock rose 805%, ahead of all 32 other companies in Oil & Gas Equipment & Services, where the typical company rose 55%.

Finding companies like these takes comparison across industries and sectors, and that is what the Trefis High Quality (HQ) Portfolio does. It holds 30 quality companies in equal weight and, since its inception in September 2020, has returned more than 105%, ahead of a benchmark that combines the S&P 500, S&P Mid-cap and Russell 2000.
