Porsche Automobil Holding SE (ISIN DE000PAH0038) stock ended Xetra trading at EUR 28.42 on September 18, 2026, a decline of 4.85 percent from the prior close as investors reacted to Volkswagen's sharp downgrade of its 2026 profit outlook and a large impairment related to Porsche.

Volkswagen warning and Porsche impairment hit the holding

As AutoNext reported on September 19, 2026, Volkswagen cut its guidance for the 2026 operating margin to a maximum of 1 percent and announced a substantial impairment tied to its Porsche stake.

According to AutoNext, Porsche SE, which holds 31.9 percent of Volkswagen, now expects an adjusted result for fiscal year 2026 between minus EUR 0.5 billion and plus EUR 1.5 billion, compared with its previous range of EUR 1.5 billion to EUR 3.5 billion.

This new corridor implies a possible swing of up to EUR 2.0 billion versus the prior guidance midpoint, underscoring how strongly the impairment and weaker Volkswagen profitability feed through to the holding company's earnings sensitivity.

Share price reaction and trading metrics

Price data from Xetra show that Porsche SE shares closed at EUR 28.42 on September 18, 2026, down from EUR 29.87 on September 17, 2026, corresponding to a daily loss of 4.85 percent after a gain of 3.97 percent the previous trading day.

Over the session on September 18, 2026, the stock traded in a range between EUR 27.98 and EUR 29.69, with reported volume of about 2.30 million shares, indicating elevated trading activity compared with the prior days.

In the 52-week window ending September 18, 2026, Porsche SE's Xetra quotation has fluctuated between levels around the upper EUR 20s and low EUR 30s per share; with the latest close of EUR 28.42, the stock is currently positioned below the recent local highs noted in mid-September 2026.

Updated outlook puts focus on earnings risk

According to AutoNext, the downward revision of Volkswagen's 2026 margin guidance and the planned non-cash impairment related to Porsche translate directly into lower expected earnings for Porsche SE.

The new adjusted result range from minus EUR 0.5 billion to plus EUR 1.5 billion for 2026 replaces the earlier expectation of EUR 1.5 billion to EUR 3.5 billion, meaning the high end of the outlook has been cut by EUR 2.0 billion and the low end by EUR 2.0 billion as well.

For investors, this widening range and lower midpoint significantly increase uncertainty around the holding's earnings profile, since a negative adjusted result would mark a clear step down compared with the previously anticipated positive outcome.

Stock level and investor perspective

As of the Xetra close on September 18, 2026, Porsche SE stock traded at EUR 28.42, reflecting the market's repricing after the revised 2026 outlook and highlighting that the shares currently sit below recent mid-September peaks while investors reassess the impact of Volkswagen's warning and Porsche-related impairments.
