Black Rock Coffee Bar (NASDAQ: BRCB) completed its IPO in September 2025 and reported 2026 first-quarter results after the market closed on May 12, 2026. Same-store sales growth slowed to 5.2% from 9.2% a year earlier, and revenue of $55.45 million missed consensus estimates. The company said new store openings led to sales shifting from older locations, affecting its same-store metric, and a law firm later filed a securities-fraud class action alleging the IPO materials were materially misleading.

Calix (NYSE: CALX) reported first-quarter 2026 results on April 21, 2026, posting a non-GAAP gross margin of 57.2%, down 80 basis points sequentially. The company also cut its second-quarter gross margin guidance to 54.25%–57.25% and said it expects its full-year non-GAAP gross margin to decline 50–150 basis points. Calix said first-quarter profit benefited from advance purchases of memory, but that supply has been exhausted and it must now buy at higher market prices, increasing cost pressure. After the update, the stock fell 14% ($6.93) to $42.65.
