Simplify's Take

What believers are saying

  • Q2 2026 revenue rose 10% to $10.1 billion, and guidance increased to $38.2 billion-$39.4 billion.
  • Repatha sales jumped 37% to $953 million in Q2 2026, with U.S. prescriptions up 50%.
  • MariTide advanced through multiple Phase 3 studies in 2026, supporting a 2027 obesity catalyst.

What critics are saying

  • Prolia sales fell 32% in Q2 2026 as biosimilars attack Amgen’s legacy cash cow.
  • FDA proposed withdrawing Tavneos in April 2026, signaling regulatory risk from integrity and efficacy issues.
  • Olpasiran now faces Novartis pelacarsen failure scrutiny; a negative 2028 OCEAN(a) readout would crush Lp(a) upside.

What makes Amgen unique

  • Repatha, Evenity, and Uplizna diversify Amgen beyond one blockbuster, per August 2026 sales.
  • MariTide targets quarterly or eight-week dosing, unlike Lilly and Novo Nordisk weekly injections.
  • Amgen’s 2027 Hyderabad Science and Innovation Center expands AI-enabled drug discovery globally.

Amgen trades at 17x 2026 earnings, but forecast margin expansion assumes MariTide success

Amgen trades at $393 per share, representing a trailing multiple of 23.3 times adjusted earnings. The biotech faces declining sales from Prolia and XGEVA, down 33% year-over-year to $1.1 billion in Q2 2026, due to biosimilar competition. Six key growth medicines grew 26% year-over-year, accounting for nearly 70% of Q2 product sales. Analysts forecast the forward multiple at 17.0 times for fiscal 2026 and 16.1 times for 2027. However, consensus assumes expanding profit margins whilst Amgen increases spending. Non-GAAP research spending is set to grow in high single digits for 2026, funding nine Phase III trials for MariTide, its obesity treatment candidate. Management warned of meaningful operating expense increases in Q3 2026. The valuation depends on margin expansion materialising during this investment phase.

Amgen's $437 olpasiran bet faces higher bar after Novartis Lp(a) drug fails Phase 3 trial

Amgen faces heightened scrutiny for its experimental heart drug olpasiran after rival Novartis's pelacarsen failed to reduce major cardiovascular events in a Phase 3 trial, despite successfully lowering lipoprotein(a) levels. The setback demonstrates that improving laboratory biomarkers may not translate to better patient outcomes. Amgen's OCEAN(a) outcomes study has enrolled 7,297 participants and is tracking heart-related deaths and procedures over roughly five years. While olpasiran uses a different design and may target different patients, pelacarsen's failure removes assumptions about the commercial value of lowering Lp(a). Amgen's shares traded at $437.23, sitting 19.54% above its estimated fair value of $365.76. The company reported $10.1 billion in second-quarter revenue and $3.5 billion in free cash flow.

Amgen's Repatha hits $953M in Q2 sales, up 37% as Cramer calls it "biggest market of all time

Jim Cramer highlighted Amgen's cholesterol drug Repatha as a key driver behind the company's 31% year-to-date rally, calling it an overlooked catalyst by Wall Street. The injectable treatment, administered every two weeks, reduces death risk by 20% in patients at high risk for heart attack or stroke. Repatha generated $953 million in second-quarter sales, up 37% year-over-year. US new prescriptions surged over 50%, split evenly between cardiologist use and primary-care adoption for high-risk patients. Cramer noted the drug works against diabetes and high cholesterol, though insurance reimbursement has posed challenges. Amgen trades at a forward PE of 19, compared to Eli Lilly's 32, whilst outperforming Lilly's 10% gain this year. Repatha is one of six growth drivers representing nearly 70% of Amgen's product sales. The company raised full-year revenue guidance to $38.2-$39.4 billion.

Amgen surges 3.5% to $440 as healthcare stocks hit record high on strong Q2 results

Amgen shares jumped 3.5% to $440.08 on Wednesday as healthcare stocks reached record highs. The biotech company reported second-quarter revenue of $10.1 billion, up 10%, whilst GAAP earnings surged 65% to $4.37 per share. Twenty-two of Amgen's medicines posted double-digit sales growth, with seventeen products generating over $1 billion in annualised sales. Six key growth products climbed 26% and now account for nearly 70% of product revenue. The rally came as investors rotated into healthcare following excitement around Merck and Moderna's melanoma breakthrough. However, Amgen now trades at a 19% premium to its fair value estimate of $365.04, putting pressure on execution as some products like Prolia face headwinds.

Amgen and Regeneron emerge as GLP-1 investment alternatives beyond Eli Lilly and Novo Nordisk

Amgen and Regeneron could benefit from surging demand for GLP-1 drugs, which traditionally treated diabetes but now address obesity and obstructive sleep apnea. Amgen's stock is up 27% this year, with second-quarter revenue rising 10% year-over-year to $10.1 billion. The company is testing MariTide, an investigational GLP-1 medicine, in phase 3 studies for weight management and diabetes. MariTide could be administered monthly or less frequently, offering a convenience advantage over current daily or weekly treatments. Regeneron is also positioned to capitalise on the GLP-1 market expansion. Both companies present alternatives to current market leaders Eli Lilly and Novo Nordisk for investors seeking exposure to the growing GLP-1 drug category.
