Weiss Ratings downgraded Mammoth Energy Services stock from sell (d+) to sell (d) in a research note dated August 11, 2026, according to MarketBeat. The rating change gives the small-cap energy services company a clear negative external assessment while its operating figures show a more mixed picture.

Rating cuts meet improving EBITDA

Mammoth generated USD 2.60 million in adjusted EBITDA from continuing operations in the second quarter of 2026, up from USD 1.90 million in the first quarter of 2026, according to Seeking Alpha. That increase of 36.84 percent contrasts with the weaker rating and shows why the stock story cannot be reduced to a single sentiment indicator.

The company operates across infrastructure services, well completion services, natural sand and proppant services, and drilling services. Its infrastructure activities include construction, maintenance and storm restoration for electric transmission and distribution systems, according to Mammoth Energy Services.

Second-quarter revenue reached USD 26.05 million

Mammoth reported USD 26.05 million in revenue for the second quarter of 2026 and a loss of USD 0.01 in earnings per share, according to MarketBeat. The revenue figure and the adjusted EBITDA improvement point in different directions, with operating progress occurring alongside continuing earnings pressure.

The second-quarter results covered the period ended June 30, 2026, and were announced on August 7, 2026, according to the company investor-relations page. The reporting period is recent enough to frame the current debate around execution, profitability and the durability of the recovery.

Stock remains below its yearly high

Mammoth Energy Services has a market capitalization of USD 136.8 million as of October 1, 2026. Its 52-week range was USD 1.72 to USD 3.92, leaving the company in the lower portion of its annual trading range despite the operating improvement.

For investors, the key contrast is measurable: adjusted EBITDA rose from USD 1.90 million to USD 2.60 million between the first and second quarters, while the latest published analyst action moved the rating from sell (d+) to sell (d). The next market reaction will depend on whether stronger operating earnings translate into sustained positive net income.

After-hours price holds above prior close

Mammoth Energy Services stock was trading at EUR 2.52 at Lang & Schwarz on October 1, 2026 at 10:54 p.m. CEST in after-hours trading, up plus 0.40 percent versus the EUR 2.51 prior close of September 30, 2026.
