About: GSK is a UK pharmaceutical company that develops, makes and sells medicines and vaccines. It reports three product groups. Specialty Medicines, about removed: 45% added: 44% of sales in removed: Q2 added: Q3 2026, includes HIV medicines from its ViiV Healthcare unit, respiratory and immunology medicines, and cancer medicines. Vaccines, about removed: 27% added: 29% of sales, includes Shingrix for shingles, meningitis vaccines and Arexvy for RSV. General Medicines, about 27% of sales, includes removed: older inhaled medicines such as removed: Trelegy, added: Trelegy and older medicines whose sales removed: fall. added: fall over time. Sales were removed: £8.4 added: £8.9 billion in removed: Q2 added: Q3 2026. GSK earns most of its profit from patented medicines, so it must replace medicines that lose patent protection with new ones from its research or from acquisitions. Its main HIV medicine, dolutegravir, loses exclusivity from 2028 to 2030.
Thesis: GSK trades at a discount because the market doubts that its new medicines can replace the HIV sales it will lose when dolutegravir patents expire from 2028 to 2030. General Medicines sales also fall, by 9% in Q2 2026, and a late-stage failure in July 2026 added to the doubt: GSK stopped camlipixant for chronic cough and took a £1.3 billion impairment. US drug-price pressure is a second concern, although GSK's December 2025 agreement with the US government gives it relief from Section 232 tariffs through January 20, 2029. GSK now buys growth with removed: debt, for example added: debt: net debt rose to £20.7 billion at September 30, 2026, after it bought Nuvalent for about $10.6 billion in July removed: 2026, and it added: 2026. It also plans removed: more than 20 added: 22 phase III trial starts in 2026. For the gap to close, GSK must win approvals and fast launches for its new medicines, keep its 2026 guidance of 7% to 9% core EPS growth, stay on track for its target of more than £40 billion of sales in 2031, and keep its operating margin stable through the dolutegravir patent expiry. removed: The near-term added: Two tests removed: are the added: passed in October 2026. The FDA removed: decision on bepirovirsen added: approved Hibsago (bepirovirsen) for chronic hepatitis removed: B, expected by added: B on October removed: 26, added: 20, 2026, added: and GSK kept its 2026 guidance in the Q3 2026 report on October 28, added: 2026. But core EPS grew only 1% in Q3 2026, added: because R&D and added: interest costs rose, and GSK expects 2026 growth in the added: lower half of its range. The next tests are the FDA decision on neladalkib for lung cancer, with a target date of November 27, removed: 2026. added: 2026, and the full-year 2026 report with 2027 guidance, expected on February 3, 2027. The gap can close only over several years, as new launches grow before and through 2028 to 2030. The main risk is that new medicines grow too slowly to replace HIV sales.
Risks: Dolutegravir, GSK's main HIV medicine, loses exclusivity from 2028 to 2030. HIV sales were £2.1 billion in removed: Q2 added: Q3 2026, about a quarter of group sales. If new HIV medicines and other launches do not grow fast enough, sales and margins fall in that period. New medicines can fail late in development. In July 2026, camlipixant failed to show enough benefit in phase III, and GSK took a £1.3 billion impairment. GSK removed: now plans removed: more than 20 added: 22 phase III trial starts in 2026, added: with 18 started by October 28, 2026, and some of them will fail. US drug prices are under political pressure. GSK agreed with the US government in December 2025 to lower some prices in exchange for relief from Section 232 tariffs through January 20, 2029, and GSK and ViiV joined the Generous Model of the Centers for Medicare and Medicaid Services from June 15, 2026. More US price rules can lower sales. Debt rises with acquisitions. Net debt was removed: £15.1 added: £20.7 billion at removed: June added: September 30, 2026, removed: before the Nuvalent purchase of about £7.1 added: up from £14.5 billion removed: net added: at December 31, 2025, mainly because of removed: cash, which added: the Nuvalent, RAPT and 35Pharma purchases. GSK funded added: Nuvalent mainly with debt. GSK removed: expected core added: expects interest removed: costs added: charges of about removed: £800 added: £700 million added: to £750 million in 2026. Zantac lawsuits continue. The Delaware Superior Court granted summary judgment for the remaining cases filed on or before December 1, 2025, on April 13, 2026, and an appeal of about 14,000 dismissed federal cases waits for a decision expected in the second half of 2026.

Recent events: Oct added: 28, 2026: GSK reported Q3 2026 results. Sales were £8.9 billion, up 5% at constant exchange rates. Specialty Medicines grew 15%, Vaccines fell 2%, and General Medicines were stable. Core operating profit grew 5%, but core EPS grew only 1%, because of higher R&D spending and higher interest costs after the Nuvalent purchase. Total operating profit fell 16%, mainly because of £328 million of restructuring charges. GSK kept its 2026 guidance of 3% to 5% sales growth and 7% to 9% core EPS growth, with core EPS growth in the lower half of that range. Net debt was £20.7 billion at September 30, 2026. Oct 26, 2026: GSK's licensor Hansoh Pharma reported a second positive phase III trial of Ris-Rez in China. In relapsed osteosarcoma, Ris-Rez lowered the risk of disease progression or death by 67% against chemotherapy. At the same ESMO congress, GSK also showed positive early data for Ris-Rez in small cell lung cancer and for Mo-Rez in ovarian cancer. Oct 20, 2026: The FDA approved Hibsago (bepirovirsen) for chronic hepatitis B, with standard antiviral treatment, in adults without cirrhosis whose virus is suppressed and whose HBsAg level is 3,000 IU/ml or lower.

Oct 19, 2026: The FDA gave accelerated approval to Jemperli (dostarlimab) for adults with stage II or III MSI-H/dMMR locally advanced rectal cancer. In the AZUR-1 trial, 68% of evaluable patients had a complete clinical response that lasted 12 months. The approval came about four months before the target date, with a national priority voucher. Sep 15, 2026: GSK agreed to buy a trispecific T cell-engager for multiple myeloma from Chimagen Biosciences. The programme should enter phase I trials in 2027.

The FDA decision in the US is expected by October 26, 2026. Jul 28, 2026: GSK reported Q2 2026 results. Sales were £8.4 billion, up 5% at constant exchange rates, and core EPS grew 9%. Specialty Medicines grew 14%, Vaccines 8%, and General Medicines fell 9%. Total operating profit fell 75% because of a £1.3 billion impairment, mainly for camlipixant. GSK kept its 2026 guidance, started a three-year plan that targets £1.9 billion of annual savings by 2029 at a cost of £2.4 billion, and raised its plan to more than 20 phase III trial starts in 2026. Jul 17, 2026: GSK stopped development of camlipixant in refractory chronic cough. Only one of two phase III trials met its main goal, and only at the higher dose. Jul 15, 2026: GSK completed its purchase of Nuvalent for an equity value of about $10.6 billion (£8.0 billion), or about $9.4 billion net of cash acquired, funded mainly with debt. The deal adds two lung cancer medicines: zidesamtinib, which the FDA approved as Jideytro in July 2026, and neladalkib, under FDA review.
