GSK plc (GB0009252882) closed at $50.27 on August 12, 2026, and MarketBeat shows after-hours trading at $50.60, up $0.33, or 0.66 percent, as of 6:43 a.m. Eastern on August 13, 2026.
The same snapshot places the shares at a market cap of $102.51 billion, while TradingKey lists a trailing price-to-earnings ratio of 12.97.
Filing and valuation
A recent filing adds a fresh watch point for traders. MarketBeat says the most recent SEC filing was a Form 6-K submitted on August 11, 2026, which keeps the stock tied to company disclosures and market reaction into the new session.
That setup matters because the valuation is still anchored to a large-cap healthcare name with a $102.51 billion market value and a P/E below 13, a combination that often leaves less room for sharp rerating without a clearer earnings surprise.
Reported results
TradingKey's analysis page lists GSK's market cap at $102.51 billion and a trailing P/E of 12.97, which gives the stock a clear earnings multiple for comparison with peers.
MarketScreener's company page shows 2025 net sales of 34.33B and 2026 net sales of 45.08B, while net income rises from 6.35B to 8.34B over the same comparison period.
The comparison is material: net sales increase by 10.75B year over year, and net income rises by 1.99B, giving investors a concrete reference point for how the latest reported business mix has shifted.
Product lens
GSK's portfolio still spans vaccines, specialty medicines and consumer health, and that mix remains the operating backdrop for the stock. A representative name in the lineup is Shingrix, which keeps vaccine demand and margin quality part of the long-term debate.
Stock level
The shares finished the latest session at $50.27, with the after-hours quote at $50.60, and the market cap at $102.51 billion gives the stock a size that keeps every filing, earnings update and portfolio shift in view.
