Celltrion said Friday its second-quarter operating profit increased 77 percent year-on-year to 430 billion won ($278.14 million), driven by a higher share of new high-margin products and an improved cost structure. In its regulatory filing, the biopharmaceutical company reported 1.3 trillion won in sales and 430 billion won in operating profit for the second quarter, both record highs for the April-June period.
