Forward-Looking Statements 3 Executive Summary (1) See slide 5 for more detail. (2) Any acquisitions would be additive to organic growth forecast of $40M in Adj. EBITDA by 2030. (3) As of 12/31/2025. (4) As of 9/21/2026. We believe Star is positioned to deliver strong shareholder returns through: Opportunistic Share Repurchases Approx. $11M repurchased since 2019; including ~8% block purchase in Q3 2025 Organic Growth We are building a diversified, scalable multi- platform portfolio of operating companies with attractive organic growth, margins, and ROIC Our $215M of usable NOLs provide a tax-efficient structure to convert EBITDA growth into FCF (3) We believe we are positioned to grow Adj. EBITDA from $6M in Q2 2026 TTM PF → $40M by 2030 (1) (2) M&A and Asset Optimization We constantly evaluate acquisition targets to supplement our organic growth goals, with a focus on growing our current platform companies (2) We believe we will monetize $20M+ of non-cash generating assets in the next few years Preference for using non-convertible preferred stock for M&A vs. common stock High Insider Ownership Insiders own ~35% (4) and buy stock regularly 4 $215M of NOLs usable against any taxable income in the US, equating to potential future cash tax savings of $45M (~$12.26/share) (4) Financial and Valuation Highlights (1) Figures are Q2 2026 TTM Pro forma – as if the acquisition of Star Operating occurred on July 1, 2025.

EBITDA by Segment (3) We are unable to reconcile our 2030 adjusted EBITDA estimate because we are unable to predict the long-term impact of foreign exchange or the mark-to-market net impact on commodity derivatives due to the unpredictability of future changes in foreign exchange rates and commodity prices. Therefore, we are unable to provide a reconciliation of these measures. Please refer to the section regarding "Forward-Looking Statements" on page 2 for more information. (1) Q2 2026 TTM Pro Forma results. See slide 35 for more detail. (2) Excluding acquisitions, we believe in our ability to: 1) grow revenue 10-15% per year on average over the next 5 years, and 2) grow Adj. EBITDA faster than that rate.

Amounts may not sum due to rounding. 2. Adjusted net income or loss per diluted share is a Non-GAAP measure defined as reported net income or loss per diluted share before items such as acquisition-related costs and non-recurring severance and professional fees after tax that is presented to provide additional information about the company’s operations on a basis consistent with the measure which the company uses to manage its operations and evaluate its performance. Management also uses these measurements to evaluate capital needs and working capital requirements. Adjusted net income or loss per diluted share should not be considered in isolation or as a substitute for net income or loss per diluted share and other income or cash flow statement data prepared in accordance with generally accepted accounting principles or as a measure of the company’s profitability or liquidity. Further, adjusted net income or loss per diluted share as presented above may not be comparable with similarly titled measures reported by other companies.
