Two months after being named CEO of Penguin Random House U.S., Madeline McIntosh has announced new roles for a number of the company’s top executives.

Among the promotions, Nina von Moltke has been promoted to president, director of strategic development, Penguin Random House U.S., and Amanda D’Acierno has been promoted to president, publisher, Penguin Random House Audio Group. In addition, Sanyu Dillon, executive v-p, director of marketing, for Random House, has been named to a new company-wide position as executive v-p, director, marketing strategy and consumer engagement, Penguin Random House, U.S. All three will report directly to McIntosh.

With Dillon’s promotion, she is assuming responsibility for the consumer marketing teams that previously reported to Amanda Close. In her memo to employees about the changes, McIntosh said Close will report to Jaci Updike, president, U.S. Sales, in a market-development capacity. McIntosh said more information on Close’s new duties will be announced soon.

In outlining the new responsibilities for the three women, McIntosh said that in her newly created role, von Moltke “will provide leadership on a wide range of topics and projects connected to our current and future content and publishing strategies, and she will work to explore new business opportunities across the market.”

D’Acierno’s promotion is a reflection of the growth of audiobook sales, which McIntosh noted “has been one of the happiest trade publishing stories of the last few years, and, thanks to Amanda and her team, we have benefited considerably from that growth as market leader.”

In her new role, Dillon, McIntosh said, “will take the lead in setting the overall direction for our consumer marketing strategy, and she will have direct oversight for corporate-level marketing operations, including our consumer acquisition, email marketing, consumer insights and analytics, partnerships, and online and social media programs and platforms.”

The changes for von Moltke and D’Acierno are effective immediately, while the changes for Dillon and Close will be effective June 18.
