Three milestones shape the story

On July 31, 2026, DiaSorin reported first-half revenue of EUR 602 million, flat at constant exchange rates versus the first half of 2025. In the second quarter, revenue grew 4 percent at constant exchange rates, while adjusted EBITDA reached EUR 194 million for the first half, down 7 percent at constant exchange rates, as Yahoo Finance reported from the earnings call.

On October 5, 2026, DiaSorin bought 40,523 shares for EUR 3,072,062.95 at an average price of EUR 75.8104. Two days later, the total program reached EUR 250 million, while treasury shares rose to 6,683,050, equal to 11.95 percent of the share capital, according to Teleborsa.

What does 32 percent guidance mean?

Management reaffirmed full-year 2026 guidance for revenue growth of 5 percent to 6 percent and an adjusted EBITDA margin of 32 percent to 33 percent. The first-half adjusted EBITDA margin was 32 percent, so the guidance depends on stronger second-half operating performance rather than a higher starting margin, according to Yahoo Finance.

Stock stays near its yearly high

DiaSorin's market capitalization was EUR 3.9 billion on October 13, 2026, while the 52-week range was EUR 52.34 to EUR 79.72. The price therefore stood 1.81 percent below the upper end of that range, leaving the buyback and the second-half margin delivery as the clearest company-specific reference points for the stock.
