Thanks, Aviv, and good afternoon, everyone. As Aviv mentioned, 4th-quarter revenue was $4 billion. Gross profit in the quarter was $2.3 billion or 58% of revenue. Sequentially, gross profit decreased primarily due to lower revenue, higher depreciation and reduced factory loadings. Gross profit margin decreased 190 basis-points.
Operating expenses in the quarter were $937 million, up 4% from a year-ago and about as expected. On a trailing 12-month basis, operating expenses were $3.8 billion or 24% of revenue. Operating profit was $1.4 billion in the quarter or 34% of revenue and profit was down 10% from a year-ago quarter. Net income in the 4th-quarter was $1.2 billion or $1.30 per share. Earnings per share included a $0.02 benefit for items that were not in our original guidance.
Let me now comment on our capital management results, starting with our cash generation. Cash-flow from operations was $2 billion in the quarter. Capital expenditures were $1.2 billion in the quarter. In the quarter, we paid $1.2 billion in dividends and repurchased $537 million of our stock. We also increased our dividend per share by 5% in the 4th-quarter, marking our 21st consecutive year of dividend increases. In total, we have returned $5.7 billion in the past 12 months-to owners.
Our balance sheet remains strong with $7.6 billion of cash and short-term investments at the end-of-the 4th-quarter. Total debt outstanding was $13.7 billion with a weighted-average coupon of 3.79%. Inventory at the end-of-the quarter was $4.5 billion, up $231 million from the prior quarter and days were $241, up 10 days sequentially.
Now let's look at some of these results for the year. In 2024, cash-flow from operations was $6.3 billion and capital expenditures were $4.8 billion as expected. We are nearly 70% through a six-year elevated capex cycle that once complete will uniquely position TI to deliver dependable low-cost 300 millimeter capacity at-scale to meet customer demand.
Free-cash flow for 2024 was $1.5 billion or 10% of revenue. Our free-cash flow reflects the strength of our business model as well as our decisions to invest in 300 millimeter manufacturing assets and inventory to support our overall objective to maximize long-term free-cash flow per share, which we believe is the primary driver of long-term value.
Turning to our outlook for the first-quarter, we expect TI revenue in the range of $3.74 billion to $4.06 billion and earnings per share to be in the range of $0.94 to $1.16. Based on current tax law, we now expect our effective tax-rate for 2025 to be about 12%. In closing, we will stay focused in the areas that add value in the long-term. We continue to invest in our competitive advantages, which are manufacturing and technology, a broad product portfolio, reach of our channels and diverse and long-lived positions.
We will continue to strengthen disadvantages through disciplined capital allocation and by focusing on the best opportunities, which we believe will enable us to continue to deliver free-cash flow per share growth over the long-term.
With that, let me turn it back to Dave.
