Amgen reported second-quarter results on Tuesday that topped expectations, raised its full-year outlook, and disclosed it was ending development of an early-stage weight loss drug candidate.
The Thousand Oaks, California-based biotech earned $2.38 billion in the second quarter, translating to $4.37 per diluted share, a significant jump from the $1.43 billion, or $2.65 per share, it recorded in the year-ago period. On an adjusted basis, earnings came to $6.29 per share, up 4% year over year. Analysts had expected adjusted earnings of $5.62 per share, according to the Wall Street Journal.
Total revenue climbed 10% to $10.05 billion, compared with $9.18 billion in the second quarter of 2025, the company said. Product sales grew 9% to $9.54 billion, driven by volume growth. Analysts had expected revenue of $9.43 billion, according to the Journal.
Among the top performers, cholesterol drug Repatha posted sales of $953 million, up 37% year over year, while bone drug Evenity generated $714 million, up 38%. Rare disease treatment Uplizna grew 90% to $335 million. Cancer drug Imdelltra rose 115% to $288 million.
Amgen lifted its full-year 2026 guidance, now targeting total revenue in a range of $38.2 billion to $39.4 billion, which compares favorably to its previous forecast of $37.1 billion to $38.5 billion. On the earnings side, the company set an adjusted EPS target of $22.30 to $23.50, stepping up from its prior range of $21.70 to $23.10.
"Our six key growth drivers grew 26% year over year, generating nearly 70% of second-quarter product sales," Chief Executive Officer Robert Bradway said in a statement. "As we expand the potential of our existing medicines through new indications and advance the next wave of pipeline molecules through Phase 3, we remain confident in our ability to deliver growth well into the next decade."
Amgen also announced it is ending work on AMG 513, an early obesity candidate that had been undergoing Phase 1 testing. No explanation for the move was given. Amgen added that the existing Phase 1 trial would run its full course so that participants already in the study can be followed through to its conclusion.
With AMG 513 discontinued, MariTide stands as Amgen's sole remaining entry in the obesity space, advancing through Phase 3 trials that span chronic weight management, Type 2 diabetes, cardiovascular outcomes, and additional indications.
Amgen generated $3.5 billion in free cash flow during the quarter, up from $1.9 billion in the second quarter of 2025. Cash and cash equivalents totaled $14.0 billion as of June 30, 2026.
Four leading AI models discuss this article
"Amgen's core growth engines are firing but its narrowed obesity bet represents a material long-term risk that the beat and guidance raise do not fully offset."
Amgen's Q2 beat (adj. EPS $6.29 vs $5.62 expected, revenue $10.05B vs $9.43B) and raised FY2026 guidance (revenue to $38.2-39.4B, adj. EPS $22.30-23.50) reflect strong volume growth in Repatha (+37%), Evenity (+38%), Uplizna (+90%), and Imdelltra (+115%). The six key growth drivers now comprise ~70% of product sales, supporting Bradway's long-term confidence. Free cash flow rose to $3.5B. However, the quiet termination of early-stage obesity candidate AMG 513 leaves MariTide as the sole pipeline bet in a market where Eli Lilly and Novo Nordisk already dominate with approved GLP-1s.
The article glosses over that discontinuing AMG 513 may signal internal data concerns or pipeline weakness in the high-growth obesity space; if MariTide Phase 3 hits any safety or efficacy snags, Amgen risks permanent exclusion from the largest new therapeutic category of the decade, capping its re-rating potential.
"Amgen’s pipeline has become dangerously concentrated, as the cancellation of AMG 513 leaves the company’s long-term growth narrative entirely dependent on the clinical success of MariTide."
Amgen’s Q2 beat is impressive, but the market is ignoring the 'single-asset risk' now concentrated in its obesity portfolio. By killing AMG 513, Amgen has effectively gone 'all-in' on MariTide. While the 10% revenue growth and 37% surge in Repatha sales demonstrate strong commercial execution, the valuation is increasingly tethered to MariTide’s Phase 3 success. With obesity being the most crowded and competitive space in pharma, any clinical hiccup or safety signal for MariTide will be catastrophic. Investors are currently pricing in a best-case scenario, ignoring the reality that Amgen is now a binary play on a single weight-loss candidate to drive long-term growth.
The discontinuation of AMG 513 could be a prudent capital allocation decision to focus resources on the higher-probability, late-stage MariTide, rather than a sign of systemic pipeline weakness.
"Amgen's core business is firing, but the obesity portfolio narrowing to a single Phase 3 candidate in a saturated market creates meaningful execution risk that the beat obscures."
Amgen's beat is real—$6.29 adj. EPS vs. $5.62 consensus, 10% revenue growth, and six growth drivers up 26% YoY is solid. The guidance raise ($22.30–$23.50 EPS vs. prior $21.70–$23.10) signals confidence. But the cash flow surge ($3.5B vs. $1.9B) warrants scrutiny: is this sustainable operational improvement or timing-driven working capital release? More concerning: dropping AMG 513 suggests obesity pipeline risk. MariTide is now the sole obesity bet in a crowded market (Novo, Eli Lilly, Viking). If Phase 3 stumbles, Amgen loses a major growth narrative. The article doesn't explain the AMG 513 termination—safety, efficacy, or strategic pivot?
The guidance raise is modest (midpoint $22.90 vs. $22.40 prior)—essentially flat—and the obesity retreat signals internal doubt about competing in a market where Novo and Lilly already have approved drugs with real-world efficacy data.
"Ending AMG 513 raises questions about the true size and durability of Amgen's obesity opportunity and suggests pipeline risk that could dominate sentiment if near-term catalysts underwhelm."
Amgen delivered solid Q2 results with 10% revenue growth, $4.37 EPS vs $5.62 est on adjusted basis, and raised full-year guidance to $38.2-39.4B revenue and $22.30-23.50 in adjusted EPS. Yet the notable pivot is ending AMG 513, an obesity candidate, which hints at safety/efficacy hurdles or a strategic retreat from a high-risk space. The core growth drivers (six) accounted for ~70% of Q2 product sales, underscoring concentration risk if any of those assets stall or face pricing pressure. Despite strong cash flow ($3.5B in FCF; $14B cash), a durable bull case hinges on pipeline catalysts and continued pricing resilience—risks exist if obesity/diabetes franchises underperform or biosimilars erode margins.
The AMG 513 termination could be a prudent refocus, and the raised guidance plus robust free cash flow imply Amgen remains financially solid with optionality from its core franchises and a healthier balance sheet.
"Amgen's diversified cash generation mitigates the obesity single-asset risk that Claude and Gemini emphasize."
Claude's cash flow scrutiny misses the bigger picture: $3.5B FCF reflects genuine operating leverage from patent-protected growth products now at 70% of sales. The modest guidance raise isn't flat—it's conservative after a 12% EPS beat. Obesity binary risk is real but overdone; Amgen's inflammation and bone franchises provide durable cash to fund multiple shots on goal beyond MariTide.
"Amgen's valuation is being mispriced as an obesity binary play, ignoring the successful integration of its rare disease portfolio which drives sustainable margins."
Gemini and Claude are obsessing over obesity, but they are ignoring the Horizon Therapeutics integration. Amgen’s ability to scale rare disease assets—like Tepezza and Krystexxa—is the real margin driver, not just MariTide. If the six growth drivers are hitting 70% of revenue, the 'binary risk' narrative is a distraction from the company's transition into a high-margin, specialty-focused powerhouse. Stop viewing Amgen as an obesity play; it is a diversified rare-disease cash machine.
"Horizon's valuation math doesn't work unless rare-disease assets hit double-digit growth—the article provides no evidence they will."
Gemini's Horizon pivot is clever but incomplete. Tepezza and Krystexxa are real, but Amgen paid $27.4B for Horizon—a 2.8x sales multiple on a ~$9.6B revenue base. Rare disease margins don't justify that premium unless those assets grow 15%+ annually. The article provides zero evidence they're tracking that. Six growth drivers at 70% of sales is concentration, not diversification. Horizon doesn't solve the MariTide binary; it compounds it.
"Horizon assets and rare-disease margins offset obesity risk; true diversification measured by EBITDA mix, not revenue share."
Gemini's 'binary MariTide' risk is a useful wake-up call, but it overstates the concentration danger as Horizon assets add optionality and could lift margins beyond MariTide's contribution. The real risk is not a single asset; it's pricing/ payer headwinds across GLP-1s and obesity, plus whether rare-disease franchises deliver durable profitability. A better panel takeaway would be EBITDA mix by asset, not just revenue share, to judge true diversification.
