Upfront Briefing

Sanofi is swapping CEOs: Paul Hudson is out, and Belén Garijo is set to step in — a very on-the-nose way to signal “strategy refresh” without writing the words.

On the capital calendar, Nektar priced an upsized $400M public offering, while Ipsen posted FY2025 results and laid out 2026 guidance — the two fastest ways to move a model (cash and numbers).

Tape Action

Instrument Last close 1D % YTD %
S&P 500 6,941.5 0.0% +1.4%
Nasdaq 100 25,201.3 +0.3% (0.2%)
Russell 2000 2,669.5 (0.4%) +7.6%
Healthcare (XLV) 156.3 +0.6% +0.9%
Biotech (XBI) 124.7 (0.6%) +2.2%
Nasdaq Biotech (NBI) 5,923.3 +0.4% +3.8%
Clinical Trials (BBC) 40.6 (1.0%) +5.3%
  • Tape was mixed: defensives held up (XLV +0.6%) as investors leaned lower-beta, while biotech lagged (XBI (0.6%)) amid ongoing financing/dilution overhang across the complex.
  • Standout mover: Clinical Trials (BBC) was the biggest swing on the day, down (1.0%) — a reminder that “pre-rev” beta still trades like risk-on/risk-off.

The Big 3

1
Sanofi CEO Paul Hudson out, Belén Garijo to step in
  • Sanofi announced a leadership change as Paul Hudson departs and Belén Garijo is set to become the new Chief Executive Officer, marking a significant transition for the company.
  • Why it matters: This reads as a board-level “reset”: leadership change typically precedes shifts in R&D governance, portfolio pruning, and capital allocation (including external BD/M&A). Near-term, it can also widen the uncertainty band on execution until a refreshed strategy is communicated.

Nektar Therapeutics prices upsized $400M public offering
  • Nektar Therapeutics has priced an upsized public offering to raise $400 million, a move that could impact the company's financial runway and valuation.
  • Why it matters: Terms matter: Nektar priced 6.6M shares at $58.00 (plus 0.29M pre-funded warrants) on the back of positive AD data (see yesterday), which likely extends runway materially — but it also sets a new dilution/valuation reference point and is a read-through on the current biotech follow-on window.

Ipsen reports FY2025 results, provides 2026 guidance
  • Ipsen has released its full-year 2025 results and provided 2026 guidance.
  • Why it matters: Ipsen’s 2026 outlook is a clean model anchor (sales growth >13% CER; core operating margin >35%), but it also flags portfolio reality — management no longer expects €500m peak sales for Onivyde and Tazverik, which can reset LT expectations.
