Light SA Q4 2025 slides: service quality drives EBITDA growth

Light reported consolidated adjusted EBITDA of R$418m in 4Q25, up 7.2% y/y, driven by distribution EBITDA rising 42.5% to R$323m while generation & trading EBITDA fell 48.2% to R$99m. Full-year CAPEX jumped to R$1.6bn (+65.6%) with Q4 investments of R$489m; cash declined to R$626m (from R$1.5bn) but total liquidity remains R$1.7bn and net debt/EBITDA is 3.13x. Operational quality improved materially (TMA -42% to 567 minutes; DEC 6.53h; FEC 3.27) even as energy consumption fell 4.7% to 6,041 GWh and non-technical losses stayed high at 23.3%, leaving outlook contingent on concession renewal and planned capital increase/debt conversion.

Analysis

The operational fixes are credible in that they address the root causes of underperformance (meter replacement, targeted loss-reduction, and contingency management), which typically convert into cleaner cash flow profiles over 12–36 months rather than instant earnings surprises. That implies the equity is being priced for execution risk on judicial reorganization and regulatory timing, not the steady-state distribution margin improvement; a successful reorg + concession renewal would compress funding costs and is therefore a high-leverage catalyst for equity holders.

Second-order winners are vendors and service contractors tied to large-scale meter rollouts and loss-reduction programs; expect reuseable capital spending (poles, meters, automation) to generate repeatable maintenance savings and lower working capital draw once theft and billing accuracy improve. Conversely, generation-exposed counterparties and firms whose earnings rely on favourable hydrology/GSF remain exposed to a multi-year structural downside if contract exits continue and distributed generation adoption accelerates.

Key tail risks and timing windows: (1) a binary concession-renewal / judicial-reorg execution over the next 3–12 months that materially changes capital structure; (2) persistent adverse hydro/GSF dynamics over the next 12–24 months that keep generation EBITDA depressed; (3) near-term liquidity shocks if investment cadence outpaces access to deleveraging mechanisms. Monitoring legal filings and tranche terms on any announced capital increase will be the fastest way to move from speculation to position sizing.

Key Decisions for Investors

• Long LIGT3 equity (small tactical position, 3–12 month horizon): asymmetric call on reorganization/concession outcome. Position size 1–2% NAV; upside scenario (>2x) if capital conversion/re-rating occurs; downside ~40–60% if dilution or continued demand erosion forces deeper restructuring. Use a hard stop or convert to a long-dated call spread if volatility spikes.
• Event-driven options: buy long-dated LIGT3 calls (12–18 month tenor) or call spreads to cap premium. This captures the binary concession/reorg while limiting cash at risk; target 3:1 asymmetric payoff if probability of a positive judicial outcome is >30% based on management guidance.
• Relative-value pair: long LIGT3 / short EGIE3 (or CPFE3) sized to neutralize market/beta exposure (6–12 month horizon). Rationale: isolate distribution-execution upside vs generator/hydrology risk. Expect positive carry if distribution margin improvements materialize; risk is sector-wide rerating that moves both.
• Credit play: buy senior Light paper or buy protection on subordinated layers (12–24 months) if spreads are available and wide. Credit upside from debt conversion or successful refinancing; downside is higher recovery uncertainty in a failed reorg. Prioritize secured tranches and require covenant coverage analysis before committing.
