Aena stock gains as DORA III plan and Bank of America target support upside

Aena stock (ISIN ES0105046009) traded at EUR 25.58 on the Madrid Stock Exchange on September 21, 2026, up 0.79% on the day and within the current IBEX 35 rally environment. According to Bolsamania on September 16, 2026, Bank of America reiterated its buy recommendation on Aena and increased its price target from EUR 30.50 to EUR 30.70, signaling confidence in the regulated investment plan and traffic growth.

DORA III plan drives investment and returns

As TradingView reported on September 21, 2026, Spain has approved the third Airport Regulation Document, known as DORA III, covering the period 2027-2031 and allowing regulated investments of EUR 9.99 billion in Aena's airport network.

According to a presentation to investors cited by La Vanguardia on September 21, 2026, Aena expects to obtain a return of 8.32% on these DORA III investments of EUR 9,991 million up to 2031, highlighting the regulated framework as a key driver of profitability over the next decade.

The same presentation indicates that passenger traffic across Aena's network is projected to reach 363 million passengers by 2031 under the DORA III assumptions, which would represent a significant increase versus current levels and support growth in aeronautical and commercial revenues, as summarized by TradingView.

Bank of America target implies double-digit upside

Bank of America sees the current regulatory clarity and traffic outlook as reasons to maintain a positive stance on Aena. According to Bolsamania, the bank raised its price target from EUR 30.50 to EUR 30.70 and reiterated a buy recommendation, estimating potential upside of 22.8% based on its valuation work.

Measured against the September 21, 2026 closing price of EUR 25.58, the new Bank of America target of EUR 30.70 implies a gain of roughly 20% from that level, underlining that the shares trade at a discount to the value the analyst house assigns under the DORA III framework and expected growth in commercial income.

The analyst note cited by Bolsamania highlights three main drivers behind the 22.8% potential upside: improved visibility on regulated returns after the DORA III approval, ongoing growth in passenger traffic, and expansion of the commercial business across the airport network.

Regulatory and inflation risks remain in focus

Alongside the upside case, Aena faces execution and macro risks around the large investment program. As Expansión reported on September 21, 2026, Aena has indicated that it would delay certain expansion projects if inflation significantly increases construction costs, in order to avoid breaching the EUR 9,991 million regulated investment cap set in DORA III.

This means that while the DORA III framework secures regulated returns of around 8.32% on the planned investments, higher inflation or cost overruns could force a rephasing of projects and potentially slow the pace at which capacity and commercial areas are expanded, as highlighted by Expansión.

The Council of Ministers approval of DORA III for Aena, mentioned in a market brief by SquawkNews on September 21, 2026, provides regulatory certainty, but also ties returns to compliance with efficiency and sustainability targets, adding another layer of operational execution risk over the 2027-2031 period.

Stock holds support after recent pullback

Technically, the share price has recently found support after a correction from record highs. A chart analysis by Expansión on September 21, 2026 notes that the roughly 12% decline from all-time highs at the end of August to the lows of the prior week has been arrested at the base of the upward channel in which the price has moved since late 2022.

The same analysis points to a technical upside target around the zone of prior annual and historical highs, between EUR 27.65 and EUR 27.80, suggesting that if the support at the channel base holds, Aena stock could attempt to retest those levels in the coming months according to Expansión.

Within the IBEX 35 on September 21, 2026, Aena's 0.79% daily gain to EUR 25.58 left it participating in the broader index advance of 0.72% to 19,696.70 points, as shown in data from Territorio Madrid, with an intraday range for the stock between EUR 25.42 and EUR 25.60 and modest positive momentum in line with other transport and infrastructure names.
