GSK just gave investors a pleasant surprise. Shares jumped 3% to 1,705p Wednesday morning after the pharma giant upgraded its 2025 profit guidance—and yes, they’ve already baked in tariff risks. While most companies are sweating over Trump’s trade policies, GSK’s playing offense. The London-based drugmaker raised its revenue forecast from 3-5% growth to 6-7%, signalling confidence despite economic headwinds. Here’s what’s driving the rally and why GSK’s latest move matters for investors.
GSK Upgrades Full-Year Guidance Across the Board
Let’s cut to the numbers. GSK didn’t just tweak its outlook—it cranked it up significantly:
- Revenue growth: Now expecting 6-7% (up from 3-5%)
- Core operating profit: Projected growth of 9-11% (previously 6-8%)
- Core earnings per share: Expected increase of 10-12% (up from 6-8%)
These forecasts already account for existing tariffs and potential European tariffs with an estimated 15% impact. GSK’s essentially saying, “We’ve got this covered.”
The company reported Q3 turnover of £8.5bn, up 7% year-over-year. What’s fueling the growth? Two standout performers.
Specialty Medicines and Shingrix Lead the Charge
GSK’s specialty medicines division jumped 16% to £3.4bn in Q3. That’s a clear signal that their pipeline’s delivering.
But the real star? Shingrix, GSK’s blockbuster shingles vaccine, which saw sales climb 13% to £800m. If you’re over 50, chances are your doctor’s mentioned it. The vaccine’s become a cash cow, and demand isn’t slowing down.
Despite the strong performance, GSK held its expected dividend steady at 64p for the year—no surprises there, just consistent shareholder returns.
The $30bn Trump Tariff Insurance Policy
Last month, GSK announced a massive $30bn investment in US research and manufacturing over the next five years. That’s roughly £4.4bn annually—nearly three times what they’re spending on R&D in the UK (£1.5bn).
Why the spending spree? Tariff avoidance. The Trump administration’s threatened sweeping tariffs on overseas pharma companies, but there’s an escape hatch: shift production stateside.
GSK’s essentially buying peace of mind. The investment will create hundreds of high-skilled American jobs in AI and advanced digital tech. Meanwhile, UK investment has grown 50% in recent years from £1bn to £1.5bn, but the gap’s obvious.
Company sources insist this isn’t a “no confidence” vote in Britain. Call it what you want—it’s a pragmatic hedge against unpredictable trade policy.
Emma Walmsley’s Farewell Tour
These results mark the final chapter for CEO Emma Walmsley, who’s stepping down after nine years at the helm. She’s handing the reins to Luke Miels, GSK’s current chief commercial officer and former Astrazeneca exec.
Walmsley’s tenure hasn’t been without controversy, but the numbers tell a solid story: improved operating performance, stronger growth prospects, and a clearer strategic direction.
“Together, we have delivered a step-change in operating performance, new prospects for growth and a clear pathway for scale patient impact and sustained shareholder value,” Walmsley said.
Translation? Mission accomplished. Now it’s Miels’ turn to keep the momentum going.
What This Means for Investors
GSK’s profit upgrade is a confidence booster in uncertain times. While competitors worry about tariff exposure, GSK’s playing the long game with strategic US investment and a strong product lineup.
The takeaway? GSK shares look attractive for investors seeking pharma exposure with built-in tariff mitigation. With Shingrix growing, specialty medicines thriving, and new leadership ready to take over, the outlook’s bullish—even if global trade gets messier.
