July 1 (Reuters) - Financial data firm FactSet FDS.N reported third-quarter profit above Wall Street estimates on Wednesday, buoyed by growth in subscriptions.

Geopolitical uncertainty owing to the U.S.-Israeli war with Iran has rattled global markets, boosting demand for FactSet's data and analytics services as investors manage risk and rebalance portfolios.

Here are more details:

• The Norwalk, Connecticut-based company posted adjusted earnings per share of $4.53 for the quarter ended May 31, above analysts' average estimate of $4.46, according to data compiled by LSEG.

• Organic annual subscription value (ASV), a measure of expected revenue for the next 12 months from all client subscriptions, rose 7.1% to $2.49 billion as of May 31.

• FactSet reaffirmed its fiscal 2026 outlook for all financial metrics.

• "While FDS maintained all FY26 guidance metrics, contrary to our and investor expectations for a raise, we view the guidance as likely conservative and positioned for an upside surprise," said RBC Capital Markets analysts in a research note.

• Meanwhile, the firm's operating margin dropped to 26.7% in the quarter, from 33.2% a year ago, largely driven by higher employee compensation costs.

• FactSet shares were down 1.8% in premarket trading. They have shed over 20% so far this year, as investor sentiment has been clouded by broader concerns that advances in artificial intelligence could disrupt the traditional financial data and analytics industry.
