ThredUp Inc (NASDAQ:TDUP) is worth watching because its second-quarter 2026 results showed faster growth and a higher adjusted profit, yet management trimmed its outlook for the rest of the year. That mix of momentum and caution is what investors in the online resale platform are weighing, according to the company's earnings release of August 5, 2026.

ThredUp runs a large online marketplace for second-hand clothing, shoes and accessories. It also sells resale technology and logistics services to other retailers and brands under a model it calls Resale-as-a-Service, whose clients' shoppers count toward the platform's buyer and order totals.

For the three months ended June 30, 2026, revenue was US$90.8 million, up 17% from US$77.7 million a year earlier. Gross profit rose to US$72.5 million, a gross margin of 79.9% against 79.5% in the same quarter of 2025.

Profitability and the buyer base

The company still made a net loss, but it was small relative to sales. Net loss for the quarter was US$5.9 million, or US$0.05 per share, compared with US$5.2 million, or US$0.04 per share, in the second quarter of 2025. Adjusted EBITDA, a non-GAAP measure that strips out items such as share-based pay, improved to US$4.8 million from US$3.0 million, lifting the adjusted margin to 5.3% from 3.9%.

Customer activity supports the revenue picture. Active buyers reached 1.77 million, up 21% year on year, while orders climbed 22% to 1.87 million. For the six months to June 30, 2026, revenue totalled US$172.4 million, net loss was US$12.4 million and adjusted EBITDA was US$7.5 million, a margin of 4.4%.

Guidance and what management said

Chief executive and co-founder James Reinhart said the second quarter exceeded the company's expectations across the board. The release also says the company lowered its second-half guidance because of continuing economic uncertainty affecting its most price-sensitive buyers, a point attributed to Mr. Reinhart.

For the third quarter, ThredUp guided to revenue of US$87.0 million to US$89.0 million, a gross margin of 78.0 to 79.0% and an adjusted EBITDA margin of about 4.0%. For the fourth quarter it expects revenue of US$85.0 million to US$87.0 million and an adjusted EBITDA margin of about 6.0%. Full-year 2026 revenue is guided at US$344.4 million to US$348.4 million, with an adjusted EBITDA margin of about 4.7%.

Put simply, the guidance implies growth continuing in the second half but at a slower pace than the 17% reported for the second quarter. It also expects stock-based compensation of about US$23.3 million for the full year, a reminder of the gap between adjusted and statutory profit.

Balance sheet

At June 30, 2026, cash, restricted cash and marketable securities totalled US$57.4 million, up US$3.0 million from the previous quarter. The company's quarterly report shows US$18.0 million of principal outstanding on its term loan with Western Alliance Bank, compared with US$18.3 million at December 31, 2025.

Risks and what to watch

The main risk is consumer demand. Management itself has pointed to pressure on price-sensitive shoppers, and a slowdown in discretionary spending could test the guidance ranges. The company also remains loss-making on a statutory basis, so the path from adjusted to reported profit matters. The quarterly report states there were no material changes to the risk factors set out in its 2025 annual report.

Third-Quarter Guidance Sets the Bar

ThredUp's second quarter delivered revenue of US$90.8 million, up 17%, and adjusted EBITDA of US$4.8 million, with active buyers up 21% to 1.77 million. Management guided to third-quarter revenue of US$87.0 million to US$89.0 million and full-year 2026 revenue of US$344.4 million to US$348.4 million, which implies growth continuing at a slower pace than the 17% reported.

The third-quarter results will show whether revenue lands inside the US$87.0 million to US$89.0 million range and whether the adjusted margin of roughly 4.0% is met. Buyer and order growth will show whether the recent pace holds, and the path from adjusted to statutory profit matters because the company still reports a net loss.
