Rio Bravo, the manager of the real estate fund RNGO11, has confirmed a new 60-month lease agreement with Busup do Brasil Tecnologia Ltda. The deal covers 1,017.27 square meters in the Demini Tower, bringing the fund's consolidated physical vacancy rate down to 18.71%.
What Happened to the RNGO11 Real Estate Fund?
On October 14, 2026, the RNGO11 real estate fund finalized a lease for 1,017.27 square meters of private area in the Demini Tower, part of the Centro Administrativo Rio Negro corporate complex in Alphaville (Barueri, São Paulo state). The new tenant is Busup do Brasil Tecnologia Ltda., a corporate mobility and transportation company that has committed to a 60-month (5-year) term.
The arrival of the new tenant marks a direct step forward in rebuilding the asset's income. The Rio Negro complex had faced pressure on occupancy since mid-year, when GOL Linhas Aéreas vacated space, pushing the fund's vacancy rate close to 25%. With the Busup lease, the vacant area has shrunk by more than 6 percentage points in a single move.
This operational progress brings immediate relief to the single-asset property's financials. As we noted when detailing GOL's departure mid-year, RNGO11 relied heavily on mitigating fixed costs such as property taxes (IPTU) and condo fees on vacant office floors. Returning those floors generated vacancy expenses that weighed on recurring operating cash flow.
How Much Does the Busup Lease Change RNGO11's Revenue and Vacancy?
Occupying the 1,017 square meters in the Demini Tower impacts the portfolio on two fronts: it cuts expenses on vacant floors and adds new rental revenue to operating results. The standard 5-year lease term secures predictable cash flow for the portfolio through the second half of 2031.
Although the announcement did not detail grace periods or potential rent discounts granted to Busup in terms of their per-unit impact, the primary effect of the contract is the elimination of ordinary expenses for that space. For high-end office floors in Alphaville, exempting 1,000 square meters from condo fees and property taxes returns significant operating margin for management to distribute to unitholders.
In recent months, the fund's distribution of earnings has remained stable at R$ 0.52 per unit. As we analyzed when reviewing RNGO11's financial results for August, net generation had benefited from the one-time use of termination indemnities. The arrival of Busup progressively replaces those non-recurring revenues with operational rental cash flow.
How Does the Fund's Recent Leasing and Occupancy History Look?
RNGO11 is experiencing a cycle of heavy tenant turnover in Alphaville. The region has shown a recovery in demand for corporate office floors, allowing management to reposition vacant floors under long-term leases. The net result of recent moves shows a fund reacting quickly to departures by major tenants.
| Date | Tenant / Event | Tower / Area | Vacancy Impact |
|---|---|---|---|
| May 2026 | AUTRON Lease (96 months) | Padauiri Tower | Drop to 17.83% |
| July 2026 | GOL Linhas Aéreas Vacates | Demini and Padauiri Towers | Jump to 24.84% |
| August 2026 | THERA Lease | Rio Negro Complex | Drop to 14.33% |
| October 2026 | Busup Lease (60 months) | Demini Tower (1,017 m²) | Adjusted to 18.71% |
This rapid recovery in occupancy contrasts with the vacancy challenges in Alphaville seen at RECT11 and other peers in the same suburban office class. As we saw earlier with the Autron lease in the Padauiri Tower, the construction quality of the Centro Administrativo Rio Negro acts as a competitive differentiator in attracting technology and service companies seeking more competitive costs per square meter than the Faria Lima and Chucri Zaidan hubs.
Is RNGO11 Worth It with a P/NAV of 0.64 and Falling Vacancy?
With units trading near R$ 54.30 on the secondary market (compared to a net asset value per unit of R$ 84.26), the market still prices the RNGO11 real estate fund at a steep 36% discount. This P/NAV level of 0.64 reflects a structural pessimism toward suburban corporate offices that recent operational performance does not support.
The risk of a drastic drop in distributions has decreased. By filling more than 1,000 square meters in the Demini Tower for 5 years, management secures the cash flow needed to defend the distribution of R$ 0.52 per unit, while the asset-value discount provides a margin of safety for investors focused on long-term income and capital gains.
For unitholders, the key point to monitor in the short term is the expiration of the grace periods on the Busup lease. Once the rent flows fully into cash, recurring operating dividends should stabilize between R$ 0.48 and R$ 0.52 per unit without the need to draw on accumulated financial reserves.
The agreement with Busup is clearly positive news. It validates the leasing liquidity of the Rio Negro complex and reduces the cash flow risk stemming from mid-year vacancy. We maintain a HOLD rating for the RNGO11 real estate fund, emphasizing that the large discount to net asset value offers favorable asymmetry for long-term-focused unitholders.
