Thank you, Liron, and good day to everyone. Revenues for the first quarter of 2024 were $14.4 million, a decline from revenues of $37.2 million as reported in the first quarter of last year. The geographical revenue breakdown over the last 12 months was as follows. North America, 82%. Europe and Israel, 15%. Far East and rest of the world, 3%.
During the last 12 months, we had 2 over 10% customers, and our top 3 customers together accounted for about 40% of our revenues. I will be presenting the rest of the financial results on a non-GAAP basis, which excludes the non-cash compensation expenses in respect of options and RSUs granted to directors, officers, and employees, acquisition-related adjustments, as well as these liabilities, financial income. For the full reconciliation from GAAP to non-GAAP numbers, please refer to the press release we issued earlier today.
Gross profit for the first quarter of 2024 was $4.1 million, representing a gross margin of 28.5%, and compared to a gross profit of $11.9 million, or gross margin of 32% in the first quarter of 2023. As discussed last quarter, for the near term, our gross margin is expected to be at the lower end of our 27% to 32% expected range, and as our revenues grow from current levels over the longer term, it will increase towards the upper end.
Operating expenses in the first quarter of 2024 were $6.8 million, compared to $7.1 million reported in the first quarter of 2023. We believe that this level represents our expected quarterly operating expenses during the rest of the year. Operating loss for the first quarter of 2024 was $2.7 million, compared to operating income of $4.8 million, as reported in the first quarter of 2023.
Net loss for the quarter was $2.4 million, compared to net income of $4.2 million in the first quarter of 2023. Loss per share in the quarter was $0.38. This is compared with diluted earnings per share of $0.61, as reported in the first quarter of last year.
Now, turning to the balance sheet. As of March 31, 2024, the company's cash, cash equivalents and marketable securities totaled $80.7 million with no debt. This represents an increase of $9.2 million just in the first quarter, a result of a positive operational cash flow of $13.3 million, net of share repurchase cost of $4.1 million.
During the quarter, Silicom repurchased approximately 250,000 shares under our current share repurchase plan. As mentioned by Liron, based on our strong balance sheet and improved cash position, we intend to continue repurchasing our shares at a full pace.
That ends my summary. I would like to hand back over to the operator for the questions-and-answers session. Operator?
