• Profitability growth was primarily driven by the strategic shift toward aviation leasing, which now accounts for three-quarters of segment adjusted EBITDA.

• Management attributed the sequential margin expansion to a higher-margin revenue mix, specifically the increased utilization of the aviation fleet compared to lower-margin sand freight.

• The company successfully transitioned its portfolio by reinvesting most of the $150 million in proceeds from 2025 divestitures into scaling the aviation fleet from 15 to 44 assets.

• Operational improvements in the Sand segment were achieved through a better sales mix between produced and brokered sand, alongside efficiency gains at the wash plant during the peak mining season.

• A lean operating model and disciplined capital allocation allowed the company to more than double adjusted EBITDA sequentially despite a decline in lower-margin revenue.

• Management emphasized that every business in the portfolio now competes for capital based on returns, with aviation remaining the priority for growth due to attractive risk-adjusted returns.

Accelerated Margin Targets and 2027 Outlook

• Full-year 2026 adjusted EBITDA margin guidance was raised to the mid-teens, reaching a strategic milestone originally targeted for 2027 roughly a year ahead of schedule.

• Management expects a seasonal softening in the fourth quarter across Sand, Accommodations, and Drilling as customers exhaust annual budgets and activity slows into year-end.

• The company projected significant growth for 2027, with adjusted EBITDA expected to increase by more than 40% compared with full year 2026 adjusted EBITDA.

• Infrastructure activity is anticipated to build meaningfully in the fourth quarter as new project awards come online and customer onboarding continues.

• Aviation revenue is expected to remain a key driver of recurring earnings as management focuses on placing the remaining 15 unleased assets on appropriate terms.
