Senior Vice President and Chief Financial Officer, Finance and Operations at Texas Instruments
Thanks, Dave, and good afternoon, everyone. As Dave mentioned, first quarter revenue was $3.7 billion. Gross profit in the quarter was $2.1 billion or 57% of revenue. From a year ago, gross profit decreased primarily due to lower revenue and, to a lesser extent, higher manufacturing costs associated with reduced factory loadings and our planned capacity expansions. Gross profit margin decreased 820 basis points.
Operating expenses in the quarter were $933 million, flat from a year ago and about as expected. On a trailing 12-month basis, operating expenses were $3.7 billion or 22% of revenue. Operating profit was $1.3 billion in the quarter or 35% of revenue and was down 34% from the year ago quarter. Net income in the first quarter was $1.1 billion or $1.20 per share. Earnings per share included a $0.10 benefit that was not in our original guidance, primarily due to the sale of a property.
Let me now comment on our capital management results, starting with our cash generation. Cash flow from operations was $1 billion in the quarter and $6.3 billion on a trailing 12-month basis. Capital expenditures were $1.2 billion in the quarter and $5.3 billion over the last 12 months. Free cash flow on a trailing 12-month basis was $940 million. In the quarter, we paid $1.2 billion in dividends and, in the past 12 months, we returned $4.8 billion to our owners.
Our balance sheet remains strong with $10.4 billion of cash and short-term investments at the end of the first quarter. In first quarter, we issued $3 billion in debt. Total debt outstanding is now $14.3 billion with a weighted average coupon of 3.8%. Inventory at the end of the quarter was $4.1 billion, up $84 million from the prior quarter, and days were 235, up 16 days sequentially.
For the second quarter, we expect TI revenue in the range of $3.65 billion to $3.95 billion and earnings per share to be in the range of $1.05 to $1.25. We continue to expect our effective tax rate to be about 13%.
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 these advantages 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.
