Earnings of $8.14 million, or $0.22 per share, marked a sharp turnaround from last year’s $5.89 million loss.

On the operational front, KULR expanded active bitcoin mining power to 750 petahash per second (PH/s) and is targeting 1.25 exahash per second (EH/s) by late summer.

Despite the top-line growth, operating losses widened to $9.45 million from $5.33 million a year earlier. Gross margin slipped to 18% from 24% due to unexpected labor costs. Selling, general, and administrative expenses reached $6.94 million, while research and development spending rose to $2.44 million.
