Nike Inc. shares were poised for their biggest gain in more than a year after the retailer's quarterly sales exceeded Wall Street estimates and bloated inventory stockpiles showed signs of improvement.

Global revenue rose 17% to $13.3 billion in the quarter ended Nov. 30, about $700 million more than analysts had projected. Gross margin, a key gauge of profitability, also exceeded expectations, and executives said year-end performance was strong.

"Our holiday season momentum has continued through the first few weeks of December, despite operating in a largely promotional marketplace," Chief Financial Officer Matt Friend said during a conference call.

The shares rose 13% at 9:34 a.m. in New York on Wednesday. If the increase holds, Nike will be set for the biggest gain since June 25, 2021, and at the current price, is poised to add more than $21 billion of market cap. The stock had declined 38% this year through Tuesday's close.

While inventories jumped 43% from a year earlier, that was a slight improvement from last quarter's 44% increase. Company executives said the number is inflated by abnormally low levels a year ago when pandemic measures in the manufacturing hub of Vietnam and long freight times disrupted retail businesses around the world.

Wedbush analysts said Nike's inventory situation is getting better with apparel clearance units declining over the past 90 days. Meaningful improvement has been seen in North America, which "is key because the domestic business had the biggest inventory glut," Tom Nikic wrote in a note.

Excess merchandise at Nike and across the apparel industry has prompted promotional activity that has eroded profitability. Nike's gross margin fell 300 basis points to 42.9% as management moved aggressively to liquidate inventory, especially in North America. The company plans to sell excess merchandise via off-price retailers through the rest of the year.

Nike upped spending on marketing in an effort to lure in more shoppers. So-called demand-creation expenses were up 8% in the quarter to $1.1 billion, mostly due to a spike in advertising.

Sales beat expectations in all regions except for China. Nike said demand for its products grew there, but it experienced significant disruption due to COVID lockdowns. Executives said they're closely monitoring the situation as the government eases its zero-COVID policy.

For the full fiscal year, which ends in mid-2023, Nike sees revenue growth in the low teens on a currency-neutral basis. The company maintained its projection that gross margin will fall 200 to 250 basis points.
