10 Stocks I’m Watching as Tricky Small-Cap Earnings Season Begins

We have mildly positive action on Monday morning as investors digest good action and recent highs. Breadth is running about 52% positive, with the Magnificent Seven trading about flat.

The most notable action is strength in data center name Nebius Group (NBIS) and chip name Micron Technology (MU) . There are also a lot of eyeballs on Palantir (PLTR) , which reports earnings after the close Monday.

My Earnings Calendar

More than 20 of my holdings are reporting earnings in the next couple of weeks. Some of the more interesting ones are Airgain (AIRG), Core Scientific (CORZ) , Xeris Biopharma (XERS) , Cullinan Therapeutics (CGEM) , Delcath Systems (DCTH) , TeraWulf (WULF) , TG Therapeutics (TGTX) , Hims & Hers Health (HIMS) , and Harrow (HROW) .

I usually see a disappointment or two during small-cap earnings season, so I am careful about position size and prepared to buy on weakness or sell into strength. These reports have little to do with overall market conditions, so the index action does not matter much. I am focused on taking advantage of volatility and gaining greater confidence about why I am holding a particular stock.

A Closer Look at Solaris

One name I am holding that reported last week is Solaris Energy Infrastructure (SEI) , which provides logistics services for oil and gas well completion. In July 2024, the company pivoted into the AI data center power space after announcing a $200 million acquisition of Mobile Energy Rentals, a Houston-based provider of mobile natural gas-powered turbines and distributed power solutions.

Solaris Energy has enjoyed rapid growth since then, and for the full year 2025, the company posted revenue growth of 99% with adjusted EBITDA rising 137%, driven by the rapid expansion of its contracted power portfolio with some of the world's largest technology companies.

In late April, Solaris Energy reported Q1 2026 results, with revenues growing 55% to $196.2 million versus the $182.2 million estimate, earnings coming in at $0.44 per share versus the $0.26 estimate, and adjusted EBITDA margins expanded to 43.9% from 36.7% a year earlier. Concurrently, the company announced a third long-term contract with a major hyperscaler for 600 megawatts, lifting total secured generation capacity to 3.10 gigawatts, roughly the output of three large nuclear reactors.

As management noted on the earnings call, the contracted capacity in place provides line of sight into earnings and cash flow for the next 10 to 15 years. In response, Stifel raised its price target to $93 and Barclays moved theirs to $86, both citing the strength of execution and the expanding contracted base.

Technically, Solaris Energy has had a solid trend since that July 2024 breakout, and after spending the latter part of 2025 and early 2026 carving out a base at highs, the shares broke out again on March 17 on the strength of the full-year 2025 earnings report.

After digesting those gains, the shares bounced off support, hit fresh highs last week, and have since been flagging down to prior resistance around $70. I like the support area around $70 and expect the stock to rest a bit.

Game Plan

We are seeing some good underlying strength on Monday morning, although oil is higher and many stocks are extended. Market players are feeling left out and continue to put money to work.

At the time of publication, TheStreet Pro Portfolio was long SEI, AIRG, CORZ, XERS, CGEM, DCTH, WULF, TGTX, HIMS, HROW.

Please note that due to factors including low market capitalization and/or insufficient public float, we consider several of the names mentioned to be small-cap stocks. You should be aware that such stocks are subject to more risk than stocks of larger companies, including greater volatility, lower liquidity and less publicly available information, and that postings such as this one can have an effect on their stock prices.
