Dell shares fell about 3% in extended trading, even as its earnings topped expectations.
An industry-wide slowdown has been intensifying with the ongoing China -U.S. trade war, and demand across industries in China has been declining.
Revenue from Dell's servers unit, its second largest business, fell about 8.8% to $4.18 billion in the first quarter. Revenue in the Infrastructure Solutions Group, host to the server business, fell 5% to $8.20 billion, missing analysts' estimates of $8.94 billion, according to FactSet.
Trade tensions have been dragging on demand across various industries in China, and tech heavyweights like Intel and Texas Instruments have spoken cautiously about it.
"Clearly the U.S.-China trade tensions are a bit of overhang on the (servers) business," Dell's chief financial officer, Thomas Sweet, told investors in a post-earnings call.
"The server business saw this dynamic of a bit softer market coupled with some very large opportunities that were extraordinarily price aggressive," Sweet told Reuters.
Dell has been planning for a potential fourth list of tariffs on Chinese products that could include notebooks and monitors, and will adjust its global supply chain as needed.
Dell's total net revenue rose 2.6% to $21.91 billion in the three months ended May 3. On an adjusted basis, revenue of $21.99 billion missed analysts' average expectation of $22.24 billion, according to IBES data from Refinitiv.
"Dell felt the impact from softness in the server market while also favoring profitability over revenue in China and some larger opportunities that became too price sensitive," Mark Cash, an analyst at MorningStar, said.
Dell swung to a profit in the quarter, reporting net income attributable to the company of $293 million, compared with a loss of $636 million a year earlier.
Excluding certain items, Dell's earnings were $1.45 per share in the quarter, beating Wall Street's expectations of $1.21.
The server business also overshadowed a 13% jump in revenue from commercial customers, which was largely due to Microsoft Corp's decision to end support for Windows 7 in early 2020.
Separately, Dell's VMware unit reported a 13% jump in revenue to $2.28 billion.
