GLP-1s and HVP Devices Drive Mix Shift

• GLP-1s contributed about 7% of first-quarter revenues, while approximately 340 Annex 1 projects and planned automated HVP delivery lines are expected to improve the product mix and lift margins over the next two years.
• According to analysts' consensus view, growth in these segments could significantly accelerate revenue and margin expansion.
  • Automated HVP device production targeted for late 2025 to early 2026 supports anticipated uptick in operational efficiency and margin improvement.
  • The projected high single-digit growth rate for Biologics HVP in late 2025 offers a potential boost, despite recent inventory destocking weighing on near-term trends.
• Consensus narrative claims the ongoing shift to higher-value, higher-margin products is a key driver for the company's expected profit growth, especially as scale and automation enhance profitability.

Share Count Declines as Margin Efforts Ramp Up

• Analysts expect the number of shares outstanding to decrease by approximately 0.71% per year over the coming three years, while profit margins are projected to grow from 16.5% to 18.9% by 2027.
• Consensus narrative notes that operational investments, including cost control and efficiency initiatives, underpin the margin improvement story.
  • Expansion into automated, higher-margin delivery systems and contract drug handling is cited as a critical enablement for more durable margins and offsetting input cost headwinds.
  • Restructuring and C-suite changes remain a watch area for investors, since execution missteps could impact margin progress and earnings predictability, tempering the expected upside.

Valuation Stretched Against DCF and Peers

• The current share price of $297.47 represents a 61% premium to DCF fair value of $184.93 and a price-to-earnings multiple of 43.5x, well above the peer average of 25.7x and sector average of 33.4x.
• Consensus narrative highlights that for the company to justify analysts’ 2028 price target of $346.91, it would need to achieve $3.6 billion in annual revenue and a future PE of 40.4x, a valuation still above industry norms.
  • Despite high-quality earnings and profit-growth projections, the steep valuation places pressure on the company to deliver margin gains and significant top-line expansion as expected.
  • The 20% upside to the target offers opportunity, but only if execution remains robust against industry pressures and margin risks.
