UPDATE 1-Nordstrom's quarterly same-store sales miss estimates

(Compares with estimates; Adds details, share price)

May 17 (Reuters) - Department store operator Nordstrom Inc reported quarterly same-store sales on Thursday that missed analysts' estimates as the company continues to face difficulties to woo shoppers in a tense retail environment.

Shares of the Seattle, Washington-based company fell 5 percent to $48.33 in after-market trading. It has risen 7.6 percent so far this year.

Nordstrom in March ended discussions with its founding family over taking the company private after failing to agree on an acceptable price.

The company's previous going-private plans came on the backdrop of the brick-and-mortar retail sector facing record number of store closures, as more shoppers abandon malls and department stores in favor of buying online.

The company's same-stores sales rose 0.6 percent in the first quarter, missing analysts' average estimate of a rise of 1.13 percent, according to Thomson Reuters I/B/E/S.

The company's net income rose to $87 million, or 51 cents per share, in the quarter ended May 5, from $63 million, or 37 cents per share, a year earlier.

Nordstrom's total revenue increased 6.2 percent to $3.56 billion, beating estimates of $3.46 billion.

Excluding items, the company earned 51 cents per share, according to Thomson Reuters I/B/E/S, beating estimates of 43 cents per share. (Reporting by Vibhuti Sharma in Bengaluru; Editing by Shounak Dasgupta)
