What stood out

The parts that mattered.

Pulled out of the filing itself, with the figures the company reported.

Top-line growth year-over-year

Margins modestly expanded
Gross profit was $942 million (computed as $2,895M revenue less $1,953M cost of services), implying a gross margin ≈32.5%; operating income of $399M implies an operating margin ≈13.8%.

What to watch

And the other side of it.

The offsets in the same document — the things a summary that only listed the good news would have left out.

Cash balance declined sequentially
Cash and cash equivalents were $393 million at March 31, 2026 versus $420 million at December 31, 2025, a decline of $27 million.
Receivables and inventory built vs Dec 31, 2025
Accounts receivable rose to $1,587 million (from $1,408 million) and inventories rose to $225 million (from $189 million), increasing working capital needs.
Equity in earnings of investees fell

Contingent consideration and potential future payouts
Contingent consideration obligations totaled $99 million as of March 31, 2026 (up from $96 million at December 31, 2025) and Haystack-related contingent payments could total up to $150 million (up to $100M tied to revenue benchmarks plus up to $50M tied to CMS coverage).
Foreign currency translation swung to a loss
Other comprehensive loss included a foreign currency translation adjustment of $(16) million in Q1 2026 versus $5 million of other comprehensive income in Q1 2025 (a $(21) million swing).

Guidance

What they said about what is next.

The 10-Q does not provide numeric revenue or EPS guidance. Management discloses the Invigorate program 'aims to deliver 3% annual cost savings,' expects the new Michigan laboratory to be operational 'during 2027,' and the Board increased the share repurchase program by $1 billion in February 2026 (approx. $1,433,481 thousand remaining authorized as of March 31, 2026).
