British pharmaceutical group GSK reported Wednesday a sharp rise in annual net profit, boosted by strong sales of HIV, respiratory and cancer treatments as it recovered from costly US lawsuits over its Zantac heartburn treatment.

Profit after tax more than doubled to £5.7 billion ($7.8 billion) compared with £2.6 billion in 2024, GSK said, as revenue rose four percent to £32.7 billion.

"GSK delivered another strong performance in 2025, driven mainly by specialty medicines," said chief executive Luke Miels, who took over from Emma Walmsley at the start of the year.

"We expect this positive momentum to continue in 2026," added Miels, who was chief commercial officer before Walmsley stepped down after nearly nine years at the helm.

Addressing journalists in an online call later, Miels said the company was in "very good shape", adding that he would look to speed up simplification of the group.

"We're going to also have an increased focus on the practical use of AI and technology," he said.

Soon after taking over as CEO, Miels announced last month that GSK was buying the US biotech company RAPT Therapeutics, which is developing a food allergy drug, in a deal valued at $2.2 billion.

GSK forecast a low double-digit increase in revenue for its specialty medicines this year, but it expects revenue from vaccines and general medicines to decline.

- 'Exciting space' -

Shares in GSK climbed near six percent around midday on the London Stock Exchange, where the top-tier FTSE 100 index was up one percent.

"There is little doubt that the sector is an exciting space, not only in terms of the leaps being made by technology but also by the major financial rewards which the larger players are chasing," said Richard Hunter, head of markets at Interactive Investor.

"The rapid evolution of AI, for example, is decreasing both discovery and development time to market and GSK is firmly in the mix with the shares having risen by 39 percent over the last year," he added.

The company's 2025 earnings rose significantly from the previous year, when it agreed to pay $2.3 billion to end lawsuits alleging that Zantac caused cancer, though the group did not admit any liability.

- US focus -

The pharmaceutical industry has faced turbulence from US President Donald Trump's tariff threats last year, aimed at encouraging investment in the United States and reducing drug prices.

GSK, along with several other pharmaceutical giants, agreed in December to lower the cost of its prescription medicines for American patients, in exchange for tariff exemptions for three years.

Ahead of the deal, GSK announced plans to invest $30 billion in the United States over five years.

The US accounted for more than half of GSK's total revenues last year, and Miels said Wednesday that the group's 2026 guidance took into account the agreed price cuts to certain treatments.

While investment is crossing the Atlantic, Miels also emphasised GSK's commitment to the UK.

"We've got 10,000 employees in the UK and we spend around £1.5 billion per year in R&D," Miels said.

"So we're heavily committed to the UK," where the company has five manufacturing sites, he said.

The "Everlasting Battery" Inside Your Joints:UConn Professor's Self-Powered Healing Material just Got Acquired

A material that turns your own movement into medicine has just landed a corporate home. PetVivo Holdings (OTCQX: PETV), a veterinary biotech and biomedical device company focused on treating osteoarthritis in dogs and horses, has acquired PiezoBioMembrane (PBM) — a startup built around a biodegradable implant that generates electricity from the everyday force of a joint in motion, and uses that charge to help regrow cartilage from the inside out. The material is the invention of Thanh Nguyen, a professor of mechanical engineering in UConn's College of Engineering, who founded PBM in 2021 to advance new implementation methods for his work with piezoelectric materials — substances that convert mechanical force into electrical energy. These materials are typically ceramics: hard, brittle, and poorly suited for medical use. But Nguyen's lab developed new forms that are so , flexible, and biodegradable, breaking down naturally within the body over time. wound healing, The materials have already shown strong potential across a range of medical applications, including tissue regeneration, implanted force sensors, and targeted drug delivery in tumor treatment. How It Works biodegradable ultrasound for In the case of arthritis, Nguyen explains, the piezoelectric materials function as an off-the-shelf product that can be implanted or injected directly into the ailing joint — with no drugs, chemicals, or cells required. The everyday force exerted on the joint generates a small electrical charge, which helps regrow healthy cartilage, mimicking the body's natural use of electricity to regenerate tissue. "The body can be electrically stimulated to regrow," Nguyen says. PBM's materials "act like a battery — an everlasting battery that works whenever there is a force applied, and vanishes safely inside the body over time." PetVivo's Vision for the Acquisition PetVivo Holdings CEO John Lai expressed enthusiasm for the merger's potential to improve the lives of companion animals globally. "PBM has developed a compelling functional biomaterials platform with the potential to support the development of multiple medical device and therapeutic product lines across both human and animal health markets," Lai said in a press release. "By combining PBM's scientific innovation with PetVivo's product development capabilities, commercialization experience, regulatory expertise, and public company infrastructure, we believe we can accelerate theadvancement of technologies that may serve as the foundation for numerous future products and strategic opportunities." For Nguyen, the deal is a chance to scale technology that could eventually benefit both animals and people. "PetVivo is an animal health company, but they do have a big passion: pushing the technology towards clinical trials for human use," Nguyen says. "That aligned perfectly with my passion for developing technology that has an impact on human life. That is why I am excited about this merger, which facilitates my passion." A Track Record of Innovation Nguyen's research sits at the intersection of medicine, micro/nanotechnology, and biomaterials. His inventions have earned him publications in prominent scientific journals and media coverage from outlets including NPR. Nguyen founded PBM during the COVID-19 pandemic, a er realizing the material he had developed could be used to create an especially effective, biodegradable face mask — one where the mechanical force of breathing generated an electrical charge that provided an extra layer of protection against viruses. PBM is not Nguyen's only venture in the acquisition pipeline. His other startup, Single-Time Microneedles (STM), is also currently undergoing an acquisition process. STM has pioneered stable, efficient vaccine delivery technology in the form of an adhesive patch. shelfNguyen's focus on biodegradable materials has translated into a remarkably diverse range of medical applications. He has received five R01 grants from the National Institutes of Health (NIH) supporting research in cartilage regeneration, bone regeneration, HIV antibody delivery systems, and biodegradable ultrasound technology to boost the effectiveness of chemotherapy for brain cancer. "Whatever we are working on, we want to show that it works very well in vitro and in vivo," Nguyen says. "Then, when we are at the point of commercialization, we set up a startup or license the technology — or maybe team up with an industry partner."
