T Man Pharmaceutical PCL vs Merck &: why the prices moved differently

• ▲

  Longevity New S-Curve and 4bn baht target TMAN set a goal of 4 billion baht revenue in 3-5 years (from 2.5 billion in 2025), adding a longevity supplement business with 15-20 new products a year and a new own brand. This gives investors a bigger growth story, which supports the share price.

  It is the main new strategic plan that reframes TMAN's growth outlook.

• ▲

  Propoliz pushed to regional and global brand TMAN is expanding Propoliz beyond 7 countries to 10+, with South Korea and Indonesia distributor deals and first Korea shipment in October, plus a celebrity 'Friends of Propoliz' campaign. More export markets and marketing mean more sales, lifting profit expectations.

  Export expansion and marketing are concrete new demand drivers for the key brand.

• ▲

  Hospital channel and OEM growth TMAN plans to raise hospital channel revenue share to 15-20% from 10%, and its OEM contract manufacturing has grown over 100%, recently adding a major customer. Higher-margin channels and bigger OEM orders support revenue and profit recovery.

  It shows where near-term growth is coming from beyond the pharmacy slump.

• ◆

  Weak first-half profit but recovery expected First-half net profit fell 7.2% to 212 million baht on higher marketing and tax costs, even as revenue rose 8.2%. Management and brokers still expect a strong second-half recovery, so the weak result is a real counterweight but seen as temporary.

  It is the key negative fact readers must weigh against the growth plans.

  Tulisokibart succeeds in hidradenitis suppurativa Merck's anti-TL1A antibody tulisokibart met its main goal in a mid-stage trial for hidradenitis suppurativa, with 72% of high-dose patients responding versus 35% on placebo.

  New licensing deal expands oncology pipeline, a key part of Merck's strategy to replace Keytruda revenue.

• ▼

  Dutch court blocks subcutaneous Keytruda in Europe A Dutch court banned Merck from making and selling subcutaneous Keytruda in eight European countries after Halozyme's patent win. The IV form is unaffected, but this blocks a key reformulation ahead of patent expiry, pressuring the stock.

• ▲

  Pipeline advances in remigromig and Keytruda combinations Merck's remigromig met its primary goal in a Phase IIb/III diabetic macular edema study, a first-in-class eye drug.

  These pipeline successes show Merck's R&D engine is producing new growth drivers beyond current drugs.

• ▼

  Keytruda faces competitive and regulatory setbacks Summit's ivonescimab cut death risk 27% versus Keytruda in lung cancer, a direct threat.

  These events pressure Keytruda's dominance and remove a near-term pipeline catalyst, weighing on sentiment.

• ▲

  Measles outbreak boosts demand for Merck's MMR vaccine A US measles outbreak with 3,471 cases and 95% in unvaccinated people increases demand for Merck's MMR vaccine. This provides a modest but steady revenue lift from an existing product.

  Pipeline triples to offset Keytruda patent cliff Merck's phase III pipeline has nearly tripled since 2021, with 20 new drug launches expected by 2030 to replace Keytruda's 2028 patent loss.

This is a direct competitive threat to Merck's biggest drug, pressuring the stock as it raises doubts about Keytruda's long-term dominance.

  This is a major competitive development that could erode Keytruda's franchise, a core part of Merck's value.

• ▲
