May 5 (Reuters) - Realty Income O.N slashed its full-year earnings outlook on Monday, as volatile market conditions could impact demand for its commercial properties.

The San Diego, California-based firm now expects 2025 net income between $1.40 and $1.46 per share, below its previous forecast of $1.52 to $1.58 per share, but with its midpoint still ahead of analysts' estimate of $1.40 apiece, according to data compiled by LSEG.

Shares of the real estate investment trust fell nearly 1% in extended trading.

The company, however, maintained its full-year adjusted funds from operations (FFO) forecast ranging from $4.22 to $4.28 per share.

Consumers, fearful of an economic slowdown amid a trade war, are already curbing their discretionary spending, which could affect the businesses of Realty Income's clients, pressuring its occupancy rate. Around a fifth of its portfolio is exposed to restaurants, gaming and other non-essential sectors.

The company owns or holds a stake in over 15,600 commercial properties across the United States, the United Kingdom and six other European countries. It leases them to more than 1,500 clients across the retail, restaurant and gaming industries.

For the three months ended March 31, it reported adjusted FFO of $1.06 per share, in line with analysts' estimates. Its revenue grew to $1.38 billion from $1.26 billion last year, also beating estimates of $1.31 billion.
