Upfront Briefing

HIV prevention just became a billion-dollar-a-quarter, KKR decided the least glamorous corner of medtech was worth $5.7B, and Merck is still buying extra innings around Keytruda. Translation: commercial beats matter, sponsors are paying up for the plumbing, and combo strategy remains oncology’s favorite sequel.

Elsewhere, earnings season is doing the heavy lifting — and with Lilly’s print landing this morning, the obesity scoreboard gets its other half before lunch.

Tape Action

Instrument Last close 1D % YTD %
S&P 500 7,736.5 1.8% 12.8%
Nasdaq 100 29,733.2 3.3% 18.0%
Russell 2000 3,037.0 1.9% 21.1%
Healthcare (XLV) 162.1 (0.1%) 4.2%
Biotech (XBI) 151.9 3.1% 25.0%
Nasdaq Biotech (NBI) 6,578.5 2.3% 15.3%
Clinical Trials (BBC) 51.1 4.3% 35.7%
  • Biotech outran large-cap pharma on a heavy earnings tape: Gilead’s PrEP franchise cleared $1B in a quarter for the first time and Amgen posted 10% revenue growth, carrying XBI 3.1% higher, while XLV was pinned by Novo Nordisk’s 6% slide on a Wegovy pill miss.
  • The broad tape closed at records on optimism over reopening the Strait of Hormuz and a blowout Palantir print (+29%), which dragged the AI complex up with it — the Nasdaq 100 added 3.3% and the S&P 500 1.8% for its first record close since early June, with Kevin Warsh’s opening weeks at the Fed keeping rate-cut bets capped.
  • Market data: U.S. cash close Tuesday, 4 August 2026.

The Big 3

1
Gilead PrEP tops $1B as Yeztugo beats forecasts
  • Yeztugo booked $232 million in Q2 against $221 million consensus, and Gilead’s HIV PrEP franchise cleared $1 billion in a quarter for the first time, doubling year over year.
  • Why it matters: A $1B quarter puts PrEP on a roughly $4B annual run rate and turns Yeztugo from a launch story into a franchise — Gilead lifted full-year HIV growth guidance to 9–10% from 8% on the back of it, against a US PrEP market growing 14%. The near-term catalyst is the 27 August PDUFA on bictegravir/lenacapavir, with a once-weekly oral lenacapavir sNDA already accepted for 2 February 2027. That cadence squeezes ViiV’s Apretude on the prevention side and builds a defensible answer to the eventual Biktarvy patent cliff. Access pricing through PEPFAR and the Global Fund caps the ex-US contribution, and the stock eased after hours on an otherwise clean print.

KKR takes Integer private in $5.7B all-cash deal
  • KKR will pay $127 per share in cash for medtech CDMO Integer Holdings (NYSE: ITGR), an enterprise value of roughly $5.7 billion including assumed debt, with close targeted by year-end.
  • Why it matters: $127 a share against $1.85 billion of 2025 sales growing 8% puts KKR at roughly 3x revenue for the plumbing behind cardiovascular and neuromodulation devices. Integer closed at $124.50 on the announcement, a 2% discount to terms — the tape is pricing completion as near-certain rather than betting on a bump. This is the third sizeable sponsor take-private in healthcare in quick succession, after Blackstone and TPG’s Hologic deal at up to $18.3 billion and American Industrial Partners’ $1.27 billion for Avanos. Private equity is re-rating device manufacturing capacity while strategics keep capital pointed at drug pipelines. The open risk is regulatory review; Goldman ran the sell side against a four-bank buyer syndicate.

Merck doubles down on sac-TMT as TL1A splits 1–1
  • Alongside Q2 results, Merck said it will run a lung cancer trial of TROP2 ADC sacituzumab tirumotecan plus Keytruda, and reported that tulisokibart missed its primary endpoint in Phase 2 systemic sclerosis-associated ILD while hitting primary and key secondary endpoints in Phase 2b hidradenitis suppurativa.
  • Why it matters: Both legs point at the same 2028 problem — Keytruda’s US patent expiry. The sac-TMT study follows OptiTROP-Lung05, where the ADC plus Keytruda cut progression risk 65% with a 70.2% ORR against 42% for Keytruda alone, though that trial ran in China without a Keytruda-chemo control, so the global study is what decides whether the ADC displaces platinum in first line. The diversification leg is patchier: Phase 3 in ulcerative colitis and now Phase 2b in HS keep tulisokibart on track as a product, but the SSc-ILD miss undercuts Dean Li’s case for TL1A as an immunofibrosis node the way TNF and IL-23 became nodes. Squeezed on both fronts by Akeso and Summit’s ivonescimab in NSCLC and Roche’s afimkibart on TL1A, with Kelun-Biotech carrying China-sourcing overhang.
