MADRID—Olga Cuenca, executive president of Spanish corporate and financial communications specialist Llorente & Cuenca, has decided to leave the firm she founded with José Antonio Llorente more than 15 years ago, and sell her shares. Llorente says he and the firm’s remaining partners in the firm will ensure business continuity following Cuenca’s departure.

Cuenca says has been forced to take this decision “due to disagreements with Jose Antonio Llorente on key issues such as strategic vision and business management, as well as the withdrawal of the founding project and values.”

Cuenca’s shares account for 40 percent of the company’s share capital, which she says have been valued at €8.5 million by independent financial analysts.

Llorente & Cuenca employs more than 200 professionals in nine wholly owned operating offices in the Iberian Peninsula and Latin America. In the previous fiscal year the company’s turnover generated through its main activities amounted to €15.75 million, up 16.6 percent. The firm also ranked number five among European mergers and acquisitions advisors by value in 2010, according to mergermarket.
