This aggressive strategy follows positive Phase 2b trial results for its ultra-long-acting injectable GLP-1 receptor agonist (RA), which showed <em>robust and continued weight loss with monthly dosing<\/em>. The study met its primary endpoint, demonstrating statistically significant weight reduction at 28 weeks with a competitive tolerability profile. Despite this progress, five participants in Arms 1 and 3 of the monthly phase discontinued treatment due to adverse events (AEs). Pfizer&#39;s CEO, Albert Bourla, has indicated that the company aims to launch its lead obesity asset, MET097, in 2028, initiating 10 Phase 3 trials this year to support this goal.<\/p>\n<p>Meanwhile, <strong>Merck &amp; Co. (<a href=\"\/stock\/MRK\">MRK<\/a>)<\/strong> delivered a strong performance in the fourth quarter of 2025, with <strong>adjusted earnings per share (EPS) of $2.04<\/strong>, surpassing analyst estimates of $2.01. The company reported <strong>total sales of $16.40 billion<\/strong>, exceeding the estimated $16.17 billion. Key revenue drivers included <strong>Keytruda, which generated $8.37 billion<\/strong>, and <strong>Gardasil, with $1.03 billion<\/strong> in revenue, both beating expectations. Looking ahead to 2026, Merck projects adjusted EPS between <strong>$5.00 and $5.15<\/strong> and sales ranging from <strong>$65.5 billion to $67 billion<\/strong>, though the sales guidance was slightly below the estimated $67.5 billion. The company&#39;s 2026 guidance does not factor in any sales from Gardasil in China and anticipates an adjusted gross margin of approximately 82%. Animal Health sales for Q4 2025 came in at <strong>$1.51 billion<\/strong>, slightly under the estimated $1.52 billion.<\/p>\n<p>In the energy sector, <strong>Marathon Petroleum (<a href=\"\/stock\/MPC\">MPC<\/a>)<\/strong> announced a robust fourth quarter for 2025, with <strong>net income reaching USD 1,500 million<\/strong>. The company&#39;s <strong>adjusted EPS of USD 4.07<\/strong> significantly outperformed IBES estimates of USD 2.88, while reported EPS stood at USD 5.12.

This comes after Zelenskyy indicated that Ukraine would &quot;adjust&quot; negotiations following a Russian strike. Separately, the UK Maritime Trade Operations (UKMTO) issued an advisory note regarding an incident 16 nautical miles north of Oman, within the inbound Traffic Separation Scheme (TSS) of the Straits of Hormuz. A vessel was hailed on VHF by numerous small armed vessels and requested to stop but ignored the request and continued its planned route.
