Jeronimo Martins Shares Surge as Biedronka Margin Beat Overshadows Sales Miss

Shares in Jeronimo Martins surged Tuesday after the Portuguese retailer's first-half 2026 results showed stronger-than-expected profitability at its key Biedronka supermarket division, reassuring investors despite a miss on top-line sales. The stock climbed 5.0% to €18.37, with the market prioritizing operational efficiency over sales growth.

Profitability Trumps Sales Weakness

The primary driver for the stock's rally was the performance of Biedronka, the company's Polish subsidiary. The unit's EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) came in 2.6% ahead of consensus estimates, signaling robust cost control and margin management.

This margin beat proved decisive for investors, who looked past a 1.6% year-over-year decline in Biedronka's like-for-like sales. The sales figure was weaker than the market's expectation of a more modest 0.4% fall. For the group as a whole, Jeronimo Martins reported:

• Total sales rose 5.1% to €18.3 billion.
• Net profit fell 3.5% to €260 million.

Analyst Confidence Provides Second Catalyst

Adding to the positive sentiment, JPMorgan reaffirmed its Overweight rating on Jeronimo Martins' stock. While the bank trimmed its price target slightly to €23.00 from €23.50, the new target still implies significant potential upside from the current trading price.

The endorsement from a major investment bank, combined with the earnings-day margin outperformance, provided a strong dual catalyst for the shares. The broader analyst community remains constructive on the company, with 18 buy ratings, three holds, and only one sell rating, according to the source.

Market Reaction

Investors reacted favorably to the results, interpreting the Biedronka margin performance as a sign that Jeronimo Martins can protect its profitability even within what the source described as a deflationary grocery environment in Poland. The stock's move pushed it significantly off its 52-week low of €16.11.

The rally appeared to be driven by company-specific fundamentals, as there were no major European macroeconomic data releases or central bank policy announcements cited as significant factors. A company webcast held Tuesday morning provided management with an opportunity to address the sales figures and reinforce its margin recovery narrative.
