CeriBell (CBLL) shares jumped over 34% in recent trading Friday after the company disclosed it was insulated from Trump tariffs until at least Q4.

The company sources manufacturing and assembly of its headband product from two vendors in China, with final quality inspection and packaging taking place in California, it said.

CeriBell said it had enough supply of finished headband products to last through at least Q3.

"Because the company accounts for product inventory cost of goods sold on a first-in, first-out basis, the company does not expect any material impact to its financial results from incremental tariffs until at least [Q4] 2025," CeriBell said in a regulatory filing.

Once the current inventory of finished goods is sold, CeriBell expects the impact to its total gross margins by 8 to 10 percentage points, based on the current tariff of 145% on all imports from China.

The company's total gross margin recorded for the year ended Dec. 31, 2024, was 87%, it said.
