Mammoth Energy Q2’26 slides: aviation-led growth drives inflection

Mammoth Energy Services (TUSK) reported Q2’26 revenue of $26.1M (+110% YoY, +19% sequential) and adjusted EBITDA of $2.6M (second straight quarter positive; +37% sequential), with adjusted EBITDA margins hitting 10% ahead of plan. The company highlighted a debt-free balance sheet with $77M cash/marketable securities ($97M pro-forma including Puerto Rico receivables) and deployed $44M in Q2’26 capex (mostly $41.2M into aviation rentals), while initiating buybacks (230,000 shares for $0.5M). It raised FY’26 guidance for a second time to revenue growth >90% vs. $44.3M in 2025 and adjusted EBITDA margins >10%, supporting shares rising more than 10% to $3.25.

Analysis

The equity move is being driven less by reported growth than by the market’s discovery of a cleaner capital story: debt-free, net-cash, and now able to recycle assets into higher-return aviation leasing. That is meaningful for TUSK because it shifts the valuation frame from cyclical services multiple to a sum-of-parts with downside support from liquidity. The catch is that the business is still small and execution-heavy; if lease rates or utilization stall, the market will quickly stop paying for the “inflection” narrative and revert to treating EBITDA as transient.

Near term, the key catalyst is not the next headline revenue print but whether the aviation fleet converts from partially leased to materially fuller utilization over the next 1-3 quarters. If management keeps monetizing assets, the stock can continue to work, but those proceeds are not the same as recurring free cash flow and may cap the multiple if reinvestment returns prove uneven. A slippage in the PREPA receivable, any slowdown in leased asset placements, or a move in used aircraft pricing would be the first warning that the balance-sheet story is stronger than the earnings power story.

Contrarian take: the market may be underappreciating how much of the upside is already embedded in asset optionality rather than operations. That makes the name attractive on pullbacks, but not one to chase aggressively after a double-digit move unless you have confirmation that recurring aviation revenue is outpacing capital deployment. BA is not a direct beneficiary; this is a secondary-market aircraft and parts monetization story, not an OEM demand signal.

Key Decisions for Investors

• Long TUSK on a pullback into the low-$3s; target a retest of the 52-week high area (~$3.90) with downside defined by a close below ~$2.80, where the net-cash support thesis starts to break.
• If options liquidity is usable, consider a 3-6 month TUSK call spread rather than outright shares to express the re-rating while limiting exposure to a utilization miss; this is a high-variance microcap, so size accordingly.
• Do not chase BA on this news; there is no material read-through to Boeing equity. If anything, treat the used-asset monetization as evidence of residual-value optionality in secondary aircraft markets, not an OEM demand catalyst.
• Set a watch item for the next quarter: aviation assets generating revenue should keep rising, and recurring rental revenue should cover a larger share of the mix. If that stalls, fade the move even if reported EBITDA remains positive.
