Thermo Fisher Scientific’s Q2-25 results show modest growth, lower margins and weaker cash conversion.
Total revenue rose 3% YoY to $10.86 b; product sales +1%, services +5%. Operating income edged up 1% to $1.83 b but margin slipped 40 bp to 16.9% after $82 m of restructuring charges. Net income attributable to TMO increased 4.5% to $1.62 b; diluted EPS climbed 6% to $4.28.
For six months, revenue reached $21.22 b (+1.6%) and EPS $8.26 (+10%). Operating cash flow fell 34% to $2.12 b as inventories (+12%) and receivables (+5%) expanded. The company repurchased $2.0 b of shares, paid $311 m in dividends and issued $2.84 b of new debt, lifting total borrowings to $35.3 b (par) while cash rose to $4.58 b.

The effective tax rate dropped to 5.6% YTD (vs 12.2%) thanks to a $153 m deferred-tax benefit on intra-entity transfers. Management expects another ~$140 m of restructuring, mainly in Laboratory Products.
Investor focus: steady EPS aided by tax gains, soft operating margin, cash-flow pressure, and higher leverage partially offset by strong liquidity.
