| 8 THE TAKEAWAY The grid can't catch up. Power is moving behind the meter. Why the Grid is Under Pressure Multiple Forces are Straining the Electric Grid and Creating Reliability Constraints Shrinking Base Load Generation Retirement of reliable coal and nuclear plants reduces steady, always-on power the grid depends on. Weather Outages & Extreme Events More frequent and severe storms, heat waves, floods, and wildfires cause outages and damage critical infrastructure. Growing Power Demand from AI & Data Centers AI, data centers, and digital infrastructure are driving rapid growth in electricity demand. Clean Tech Manufacturing Boom Domestic manufacturing of Evs, batteries, solar, wind, and other clean tech is driving new industrial load. Grid Constraint Supply can’t keep up with demand, and the grid can’t always deliver power where and when it’s needed. |

This analysis has not been independently verified and is provided for illustrative purposes only. Actual results may vary materially based on site-specific factors, fuel costs, maintenance profile, equipment configuration, utilization, permitting, incentives, downtime assumptions and thermal-recovery use. Advantage Drivers Capstone’s higher install costs more than offset by total system value across uptime, maintenance and thermal utilization. Availability/Uptime Fewer maintenance interruptions can support greater operating availability which drive a 6.5% increase in kWh production all while also lowering downtime-related cost. Planned Maintenance Fewer service maintenance events and significantly less wear components help lower maintenance cost and increase uptime. Thermal Recovery Savings Useful heat can be converted into hot water, chilled water or steam, improving overall system economics.

This non-GAAP financial measure is among the indicators management uses as a basis for evaluating the Company’s financial performance as well as for forecasting future periods. Management establishes performance targets, annual budgets and makes operating decisions based in part upon this metric. Accordingly, disclosure of this non-GAAP financial measure provides investors with the same information that management uses to understand the Company’s economic performance year-over-year. EBITDA is defined as net income (loss) before interest, provision for income taxes and depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA before stock-based compensation, restructuring, financing, shareholder litigation and non-recurring legal, restatement and SEC investigation expenses, acquisition and reorganization items. Restructuring expenses relate to the Chapter 11 bankruptcy filing and financing expenses related to the evaluation and negotiation of the Company’s senior indebtedness. Shareholder litigation expense resulted from the restatement of the Company’s financials and non-recurring legal expenses are one-time non-recurring legal fees. Restatement expenses are professional fees related to the restatement of the Company’s prior year financials. SEC investigation expenses relate to the costs arising from the restatement of the Company’s financials. Reorganization items represent adjustments occurring during the bankruptcy period. Acquisition expenses relate to the acquisition of Cal Microturbine. Adjusted EBITDA is not a measure of the Company’s liquidity or financial performance under GAAP and should not be considered as an alternative to net income or any other performance measure derived in accordance with GAAP, or as an alternative to cash flows from operating activities as a measure of its liquidity. While management believes that the Company’s presentation of Adjusted EBITDA provides useful supplemental information to investors, there are limitations associated with the use of this non-GAAP financial measure. Adjusted EBITDA is not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to potential differences in the methods of calculation. The Company’s non-GAAP financial measure is not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP. |

| Capstone 800 VDC Roadmap Simple Component Modification & Transition from VAC to VDC The current Capstone microturbine system relies on double conversion from high frequency AC to DC, then from DC to low voltage AC (e.g. 480VAC at 60 Hz). The new High Voltage Direct Current (“HVDC”) microturbine system will have higher efficiency via single conversion of the turbine generator AC power directly to a HVDC microgrid. KEY ADVANTAGES: No AC grid required – TRUE stand-alone microgrid solution Quicker response to load changes vs traditional reciprocating engine generators Cleaner power through inverter-based power electronics Built-in redundancy and backup BESS for load transients and Microturbine bay service No exhaust after treatment, motor mounts, heat rejection radiator, sound attenuation, enclosure High combined cycle efficiency through heat recovery of high-quality exhaust CURRENT MICROTURBINE PKG FUTURE MICROTURBINE HVDC 30 |
