Auren Energia (B3: AURE3), the renewable power generator controlled by Votorantim and CPP Investments, reported a Q1 2026 net loss of R$601.6 million ($119M), reversing a R$54 million profit a year earlier, according to the company’s CVM filing released Wednesday May 6.
Adjusted EBITDA fell 23.2 percent to R$925.9 million ($183M) as total generation declined 16.6 percent to 3.33 GW average, with hydro down 20 percent, wind down 16 percent, and solar down 8.9 percent, per the earnings release.
CEO Fabio Zanfelice told Reuters the quarter’s “main highlight” was modulation gains of R$97.2 million — five times the prior year — which fully offset the R$86.2 million curtailment impact, demonstrating the value of a diversified hydro-wind-solar portfolio.
Leverage rose to 5.2x ND/EBITDA from 4.8x at year-end, with deleveraging expected to accelerate only from 2027.
Key Points
What Auren Reported in Q1 2026
Auren Energia is Brazil’s third-largest power generator with 8.8 GW installed capacity across hydroelectric (54%), wind (36%), and solar (10%) assets, formed through the 2024 merger of Auren (ex-CESP) and AES Brasil. The company is controlled by Votorantim S.A. (37.74%) and Canada Pension Plan Investment Board (32.06%), led by CEO Fabio Zanfelice, and is Brazil’s second-largest energy trader. Auren Q1 2026 results are covered by The Rio Times as part of its Latin American financial news reporting on B3-listed energy companies.
The R$601.6 million net loss requires decomposition. The operating EBITDA decline (R$925.9M, -23.2%) reflects genuinely weaker generation conditions — ONS restricted hydro dispatch to recover reservoirs, winds were below seasonal averages, and solar resource declined. But the chasm between EBITDA and the bottom line was widened by non-cash mark-to-market adjustments on forward energy contracts, which are accounting entries that do not affect cash flow and will reverse as contracts settle at delivery, according to the filing.
The modulation story is the structural insight. Modulation gains — profits captured by trading hourly price differentials between day (when solar/wind depress prices) and evening (when hydro dispatch is called to meet peak demand) — reached R$97.2 million, five times the R$19.4 million achieved in Q1 2025, per the company’s disclosure. CEO Zanfelice told Reuters this dynamic “fully compensated the curtailment impact” of R$86.2 million, producing a net positive. As long as Brazil’s electricity system features large hourly price swings — which are structural given the growing share of intermittent renewables — Auren‘s diversified hydro-wind-solar portfolio can monetise the arbitrage, a capability that pure-wind or pure-solar generators cannot replicate.
Why Auren’s Q1 Result Matters
The curtailment crisis is the defining challenge for Brazilian renewable generators in 2026. Grid-operator-mandated cuts reached 13.4 percent for wind and 16.3 percent for solar in Q1, broadly in line with system-wide averages of 14.9 and 16.2 percent respectively — but sharply above the 8.3 and 12.9 percent rates observed a year earlier, per the operational data. For a company with 3.2 GW of wind and solar capacity, every percentage point of curtailment translates directly into lost revenue and below-contracted generation, forcing energy purchases on the spot market for contract fulfilment.
Auren’s ability to turn modulation into a net profit against curtailment — R$97.2M gain vs R$86.2M cost — validates the strategic logic of the AES merger. The diversified portfolio combining Porto Primavera (2.66 GW hydro), wind complexes in the Northeast, and solar assets creates an hourly arbitrage capability: when wind and solar are curtailed at midday (depressing prices), the hydro assets are held back; when evening peak demand arrives, hydro is dispatched at elevated prices. CEO Zanfelice stated he expects modulation gains to “continue exceeding curtailment costs” going forward, though acknowledged this “depends on the quarter and system configuration.”

How It Reframes Auren’s Investment Case
The investment thesis for Auren is a patience trade: the near-term P&L is noisy (mark-to-market swings, curtailment, lower dispatch), but the underlying asset franchise — 8.8 GW of diversified renewables with the modulation capability — is structurally sound. The 5.2x leverage is elevated but manageable because it is entirely a consequence of the AES acquisition debt, not operational deterioration. CFO Ferreira confirmed that the indicator should “remain around 5 times throughout 2026” before inflecting downward in 2027 as Cajuína 3 begins generating cash and the AES integration capex winds down.
CEO Zanfelice’s energy price outlook was constructive: “I don’t see any disruption in energy prices for the coming months. Prices should remain elevated, reflecting the structural issues of power system operation.” The caveat is El Niño — forecast with 80 percent probability for H2 2026, per NOAA — which could bring above-average rainfall to the South (positive for hydro) but below-average to the Northeast (negative for wind resource). For a company with major hydro capacity at Porto Primavera (Southeast) and wind assets concentrated in the Northeast, the El Niño scenario produces mixed operational effects.
What Happens Next for Auren
Corporate reorganisation: CESP incorporation to consolidate all hydro assets in a single vehicle by end-2026. CFO Ferreira described it as “an important economic move” that will simplify structure, improve cash management efficiency, and reduce the number of publicly-listed controlled entities.
Cajuína 3 commissioning: The 112 MW wind project in Rio Grande do Norte is at 68 percent physical completion, with commissioning planned for H1 2026 and full commercial operation by December. This will add to generation capacity and contribute to EBITDA from H2.
Battery storage auctions: Management has flagged interest in ANEEL’s upcoming capacity reserve and battery auctions, using Porto Primavera hydro as the anchor asset. This would position Auren in the nascent Brazilian energy storage market.
El Niño impact: The 80 percent probability forecast could improve Southeast hydro inflows (supporting Porto Primavera) while reducing Northeast wind resource, creating a net effect that depends on the seasonal distribution across Auren’s geographically diversified portfolio.
Frequently Asked Questions
Why did Auren swing to a loss in Q1 2026?
Auren’s R$601.6 million net loss was driven by two factors: a 23.2 percent decline in adjusted EBITDA to R$925.9 million from lower hydro, wind, and solar generation across the portfolio, and non-cash mark-to-market adjustments on forward energy contracts that deepened the bottom-line impact beyond the operational deterioration. The mark-to-market effects will reverse as contracts settle at delivery.
What is modulation and why does it matter for Auren?
Modulation is the profit captured by trading hourly electricity price differentials. When solar and wind depress midday prices, Auren holds back hydro generation; when evening peak demand arrives, hydro is dispatched at elevated prices. In Q1 2026, modulation gains of R$97.2 million fully offset the R$86.2 million curtailment cost, producing a net positive of R$11 million. This capability requires a diversified portfolio and is not available to pure wind or solar generators.
When will Auren’s leverage improve?
CFO Mateus Ferreira said leverage should remain around 5.0 times net debt to EBITDA throughout 2026, with a more pronounced reduction beginning in 2027 once the Cajuína 3 wind project begins generating cash and AES integration capex ends. The long-term target is 3.0 to 3.5 times. Net debt declined R$135 million in Q1 despite the loss, indicating cash generation remains positive at the operational level.
