Brazil’s Sabesp Profit Surges 87% as Privatization Drives Efficiency
Sabesp Q4 2025 Earnings: What Happened
Companhia de Saneamento Básico do Estado de São Paulo — SABESP (SBSP3/SBS) is Latin America’s largest water and sanitation utility, serving approximately 28 million people across 375 municipalities in São Paulo state through 9.5 million water connections and 8.2 million sewage connections. Sabesp Q4 2025 earnings are covered by The Rio Times as part of its Latin American financial news reporting on B3-listed utilities.
The company reported net income of R$2.68 billion ($513M) for the fourth quarter of 2025, surging 87.1% from R$1.43 billion in Q4 2024. The headline figure includes accounting effects from the asset bifurcation model adopted following Sabesp’s July 2024 privatization, which transferred control to Equatorial Group. On an adjusted basis — stripping out these non-recurring items — net income was R$1.9 billion ($363M), essentially flat year-over-year.
Reported EBITDA reached R$4.42 billion ($846M), up 92.8%, while adjusted EBITDA came in at R$3.4 billion ($650M), a 13% expansion driven by roughly 10% cost reductions and a 3% rise in billed water and sewage volumes. Adjusted net revenue grew 2.1% to R$5.68 billion ($1.09B). Earnings per share of R$3.07 crushed the R$1.63 consensus estimate by 88%, though much of the beat reflects the accounting complexity still flowing through post-privatization results. Shares of SBSP3 traded near their all-time high of R$141.40 reached in December 2025, with the company’s market capitalization at approximately R$92.6 billion ($17.7B).
Key Drivers Behind Sabesp’s Q4 2025 Results
Post-Privatization Efficiency Revolution
The 13% adjusted EBITDA expansion was powered by broad-based cost discipline implemented since Equatorial Group took operational control in mid-2024. General and administrative expenses fell meaningfully, reflecting workforce optimization — headcount dropped approximately 13% from 10,586 to 9,279 employees between Q3 2024 and Q3 2025 — along with energy cost savings from migration to Brazil’s free electricity market and leaner operational processes across the 375-municipality concession area.
CFO Daniel Szlak attributed the revenue growth to the phase-out of legacy bulk discounts for large commercial and industrial clients, combined with the steady addition of new customers through the universalization program. However, he flagged a counterbalancing effect: roughly 20% of residential customers now receive subsidized tariffs, nearly double the share from a year earlier, partially offsetting pricing gains.
Record Capital Expenditure Blitz
Sabesp deployed R$15.2 billion ($2.91B) in capital expenditure during 2025, a 120% increase from R$6.9 billion in 2024 and roughly four times the pre-privatization average of R$3–4 billion annually. The company is connecting approximately 2,400 new households per day, having surpassed its Water Economies target by 52% and Sewage Economies target by 33% for the 2024–2025 regulatory period.
By late 2025, Sabesp had delivered potable water to over 616,000 new units, sewage connections to nearly 734,000 units, and sewage treatment to approximately 949,000 units — numbers that put it firmly ahead of the trajectory required by Brazil’s 2029 universal sanitation mandate. The work backlog stands at R$39 billion in contracted projects through 2029.
Aggressive Capital Structure Transformation
To fund the R$70 billion ($13.4B) investment plan through 2030, Sabesp raised approximately R$19 billion ($3.6B) in capital during 2025, including its first international bond issuance in 12 years. Of the total R$70 billion plan, R$40–50 billion is expected to come from debt financing. By Q3 2025, 59% of Sabesp’s debt matured from 2030 onwards, and the company held R$11.6 billion in cash covering more than four years of amortizations. Leverage remained controlled, with net debt-to-EBITDA in the 1.9–2.3x range.

Sabesp Q4 2025 Financial Detail
Revenue and Profitability
Adjusted net revenue of R$5.68 billion ($1.09B) grew 2.1% year-over-year, a modest but meaningful increase for a regulated utility that derives pricing power primarily from tariff adjustments. Reported EBITDA surged 92.8% to R$4.42 billion ($846M) while adjusted EBITDA expanded 13% to R$3.4 billion ($650M) — the gap reflecting continued distortions from the concession asset bifurcation model adopted post-privatization. For FY2025, adjusted net revenue reached R$22.2 billion ($4.25B), up 2.2%, while EBITDA totaled R$13.2 billion ($2.53B), rising 16.6% and demonstrating consistent quarterly improvement throughout the year.
Annual adjusted net income climbed 22.1% to R$6.3 billion ($1.21B), driven by cost efficiencies that Szlak described as instrumental in expanding profit even under Brazil’s 15% Selic rate environment. Reported full-year net income of R$8.46 billion ($1.62B) declined 11.7% from 2024, but that comparison is distorted by R$5.28 billion in one-time accounting gains recognized in Q3 2024 when the bifurcation model was first adopted.
Shareholder Returns
The board approved the payment of interest on capital (JCP) alongside Q4 results, with the ex-date set for March 19, 2026. This follows a R$1.79 billion JCP distribution announced in December 2025, equivalent to R$2.63 per share before the 15% withholding tax. The board also authorized a capital increase of R$2.81 billion via capitalization of retained earnings, with the issuance of 20.3 million new shares distributed proportionally to existing holders. The dividend yield stood at approximately 4.2% for 2024, with payout at 26.6%.
Management Signals from Sabesp
CFO Daniel Szlak characterized 2025 as a transformational year, emphasizing that the company reduced costs by 13% annually while simultaneously deploying record investment. The efficiency agenda delivered improvements across key operational ratios, with return on invested capital reaching 10% and return on equity hitting 14% — metrics that reflect the structural uplift from private management.
The EMAE acquisition — approximately R$1.13 billion ($216M) for a 70.1% stake in São Paulo’s metropolitan energy and water asset company — remains pending regulatory approval from CADE and ANEEL. If closed, the deal would give Sabesp control of critical reservoir infrastructure around the Billings and Guarapiranga systems, plus EMAE’s 889-megawatt Henry Borden hydro complex with long-term, inflation-indexed power contracts.
Management signaled that universalization could be achieved ahead of the 2029 deadline, citing the company’s pace of connections — already surpassing annual regulatory targets. The shift from public procurement to a fragmented private contracting model has attracted more suppliers and reduced execution risk, while the contracted work backlog of R$39 billion provides multi-year visibility on the capex pipeline.
What to Watch Next for Sabesp
The sustainability of the capex ramp is the critical question for 2026 and beyond. With R$15.2 billion deployed in 2025 and R$40–50 billion in additional debt financing planned through 2030, leverage management becomes paramount. Net debt-to-EBITDA has edged up from 1.7x in Q1 to the 1.9–2.3x range, and investors will watch whether tariff revisions and expanding revenue from new connections can keep pace with the debt load.
The BCB’s March 18 rate decision is immediately relevant. While the Selic stands at 15%, the central bank is widely expected to initiate an easing cycle in 2026 as inflation moderates. Lower rates would reduce Sabesp’s cost of debt — a meaningful benefit given the scale of its borrowing program — and potentially support utility valuations more broadly.
The EMAE deal closure, the December 2025 tariff adjustment recently approved by ARSESP, and the first full year of results under purely private management will provide clearer signals on whether Sabesp can sustain the trajectory that earned it an 88% earnings beat and near-unanimous analyst buy ratings. With 13 of 15 analysts recommending the stock and an average 12-month price target of R$146–152, the market is pricing in continued execution.

Risks Facing Sabesp
Leverage trajectory is the primary risk. With R$40–50 billion in additional debt planned and capex running at four times pre-privatization levels, any delay in tariff adjustments, regulatory pushback on rate increases, or slower-than-expected revenue growth from new connections could pressure the balance sheet. Net debt-to-EBITDA has already risen from 1.7x in early 2025 to the 1.9–2.3x range.
Water security remains a structural concern. The company implemented progressive night-time pressure reductions in late 2025 amid low reservoir levels, echoing the 2014–2015 water crisis. Climate variability, inadequate rainfall, and growing demand from the expanding customer base could strain the system, particularly if universalization accelerates sewage treatment volumes without corresponding water supply additions.
Political risk persists. Governor Tarcísio de Freitas, widely seen as a 2026 presidential candidate, championed the privatization as a signature reform. If the political environment shifts or service complaints escalate — as they did following tariff adjustments and water restrictions in late 2025 — regulatory pressure could intensify. The privatization itself still faces legal challenges from opposition parties, though courts have thus far upheld the process.
Brazilian Water and Sanitation Sector Context
Brazil’s 2020 Legal Framework for Sanitation (Marco do Saneamento) set a 2033 national deadline for universal water and sewage services — a target that remains far off in most states. São Paulo is further ahead than most, but Sabesp’s own mandate under the privatization contract is more ambitious: 2029 universalization, backed by contractual penalties if targets are missed. The company’s performance in 2025, exceeding targets by 30–50%, suggests the deadline is achievable and may even come early.
Sabesp’s privatization in July 2024 was the largest public offering in the Americas that year, raising R$14.7 billion ($2.8B) with R$187 billion in institutional demand. It transformed the utility from a state-controlled enterprise — with a history of political appointments and underinvestment — into Brazil’s first fully privatized, publicly traded sanitation company. The shift has produced immediate operational improvements: a 13% workforce reduction, migration to free-market electricity pricing, and the fragmentation of large procurement contracts to attract more suppliers and compress timelines.
The sector is attracting growing investor interest as other states consider similar privatization models. Copasa in Minas Gerais is frequently mentioned as the next candidate, and CFO Szlak has publicly signaled Sabesp’s interest in participating in future concession opportunities. With a P/E of approximately 8.4x — well below the global water utilities average of 16.2x — Sabesp offers a compelling valuation for investors who believe the execution can continue at the current pace.
