At a medical meeting last winter, a drug-industry executive flipped his nametag around so he could have more open conversations with the liver-disease scientists who were presenting their research.

"They didn't recognize who I am. No one does," recalled John Milligan, who a few months later was named chief executive of Gilead Sciences Inc.

Dr. Milligan may find it increasingly difficult to stay so anonymous as he settles into the pilot seat at Gilead, a company that has catapulted into one of the industry's biggest sellers and most controversial drug pricers.

Since the company started launching costly new hepatitis C treatments in 2013, Gilead sales have risen nearly 3½ times to $32.2 billion last year, and shares have jumped more than 130% since then. The company's Sovaldi and Harvoni commanded the biggest drug launches ever, as 920,000 patients world-wide lined up for the promise of a cure.

Yet Gilead has more recently been forced to heavily discount the hepatitis C pills to cope with mounting competition, and faces questions about the market's long-term prospects as more patients get cured.

Scrutiny over the drugs' $1,000-a-day list price lingers, despite the discounting. Gilead has faced heavy criticism and a Senate probe. Massachusetts is also investigating whether the high prices violate state laws on unfair trade practices.

Meantime, the company's HIV/AIDS franchise is aging.

Given such pressures, some on Wall Street question the company's ability to keep up its heady pace of growth. Gilead shares trade at less than eight times consensus earnings, a lower multiple than any peer, according to Geoffrey Porges, a Leerink Partners analyst.

"The stock is trading as if it is facing an existential threat that will result in a 30% to 40% erosion of its earnings," says Dr. Porges, who recommends buying the stock. Many investors would feel much better, he says, if Gilead added a new franchise to its lineup.

Dr. Milligan, a trained biochemist who is a 26-year veteran of Gilead, is tasked with finding that next source of growth and shoring up faith that the company can continue delivering blockbusters.

Investors have been looking for a new deal with the same kind of impact as the $11 billion acquisition of Pharmasset Inc. in 2012, which netted Gilead its lucrative hepatitis C franchise. But industry officials such say such transactions are hard to find, especially with biotech valuations relatively high.

He also must address the company's negative public image around pricing, no easy task for a longtime insider.

"The lesson is we have to do a lot better job talking about the value we provide," Dr. Milligan says.

Dr. Milligan, who brings home science journals to read and watches TED talks in his spare time, says he intends to stay on top of the science of drug discovery because it is so crucial in identifying new growth opportunities. Gilead is investing nearly $3 billion on R&D. And he will keep attending medical meetings, such as the liver-disease conference last November, and peppering researchers with questions.

Dr. Milligan says he isn't counting on another deal of the scale of the Pharmasset transaction. "My preference is to stay with the smaller series of acquisitions for the company, rather than trying to solve it all at once. But I reserve the right to change my mind."

Among the diseases that Gilead is targeting through a combination of in-house research and deal-making are a liver condition called nonalcoholic steatohepatitis, or NASH, and immune-system disorders like rheumatoid arthritis. Gilead is also in cancer.

"Rather than having one opportunity, I would like to have multiple opportunities for the future," Dr. Milligan says. The idea isn't to find the single next "big thing, like Pharmasset, but work three different angles that would all be growth" drivers.

Dr. Milligan says he wants Gilead to remain a lean, focused drugmaker, and avoid the pitfalls of bigness, such as large committee meetings that go on far too long and interminable email chains. Spaces still aren't assigned in the parking garage at Gilead's Foster City, Calif., headquarters, and Dr. Milligan says he regularly eats lunch in the corporate cafeteria so he can chat directly with staff. Dr. Milligan wants to keep the company's employee count, now about 8,000, relatively low.

"I'm a little maniacal about preserving the culture," he says.

He says he was inspired by two figures: his father, David Milligan, who was a chief scientific officer at Abbott Laboratories, as well as his father's boss George Rathmann, who went on to run pioneering biotech Amgen Inc.

Dr. Rathmann, he says, showed how a biotech executive can stay on top of scientific developments and let them drive decision-making. "If I'm close to the science, it means everyone else will stay close to the science as well," Dr. Milligan says.
