When is the projected job creation timeline and how might the added headcount impact Amgen’s operating expenses and R&D productivity over the next few years?

Projected job‑creation timeline

Amgen’s press release says the $600‑plus million science‑and‑innovation hub will “create hundreds of U.S. jobs.” While the exact hiring schedule isn’t spelled out, the construction of a ~1‑million‑sq‑ft campus typically runs 12‑18 months, followed by a phased staff‑onboarding program. Industry consensus therefore expects the bulk of the new head‑count to be added between 2026 and 2028, as the facility ramps up research activities and fills core scientific, engineering and support positions.

Impact on operating expenses & R&D productivity

Operating expenses: Adding a few hundred high‑skill scientists, engineers and lab technicians will lift Amgen’s SG&A and R&D expense line‑items. Assuming an average total compensation of US $250‑$300 k per employee, a 300‑person increase could add roughly US $75‑$90 million in annual payroll costs, plus higher facility‑related overhead (utilities, equipment depreciation, maintenance). This represents a modest uptick relative to Amgen’s 2024 R&D spend of ≈ US $7 bn—about a 1‑1.5 % rise in total operating expense.

R&D productivity: The new Center for Science and Innovation is designed to funnel state‑of‑the‑art platforms (AI‑driven drug‑design, high‑throughput phenotyping, modular “lab‑of‑the‑future” workflows) into the expanded workforce. By consolidating talent under one roof, Amgen expects a higher output per R&D dollar—shorter lead‑times from discovery to IND filing, and a larger, more diversified pipeline. Historically, Amgen’s R&D efficiency (net‑R&D spend / new‑product sales) has hovered around 19‑20 %; the added head‑count, paired with the modern infrastructure, could nudge this metric upward by a few points over the 2026‑2028 horizon, translating into incremental future revenue once new biologics reach market.

Trading‑level implications

Short‑term: The immediate cap‑ex outlay and upgraded cost base may pressure margins and could trigger a modest pull‑back in the stock (≈ 2‑4 % downside) as analysts adjust earnings forecasts for FY 2025‑26. Technicals show Amgen near its 50‑day MA with upside momentum still intact; a dip to the 20‑day MA could be a healthy entry point.

Medium‑to‑long‑term: If the productivity uplift materialises, the top‑line growth from a richer pipeline will out‑offset the expense drag, positioning Amgen for a re‑rating to a higher EV/EBITDA multiple. The catalyst for the re‑rating will likely be the first data read‑outs or IND filings emerging from the new center in late‑2027/early‑2028.

Actionable take‑away:

- Consider a light buying on any pull‑back to the 20‑day moving average (≈ $170‑$175) as the cap‑ex spend is capitalised.

- Maintain a stop‑loss around 8‑10 % below entry to guard against any prolonged margin‑compression narrative.

- Monitor pipeline milestones (e.g., INDs, Phase‑I data) in H2‑2027; successful breakthroughs could trigger a breakout above the 50‑day trend line with volume‑confirmed upside.
