Senior Vice President and Chief Financial Officer at Skyworks Solutions
Thanks, Liam. Skyworks. Revenue for the third fiscal quarter of 2023 was $1.071 billion, slightly above the midpoint of our outlook. Mobile was approximately 59% of total revenue with growth content gains across our largest customer product portfolio offset by ongoing weakness in demand from the Android ecosystem as these OEMs continue to reduce inventories. Broad markets were approximately 41% of total revenue. We have another strong contributor --contribution from the automotive infrastructure and industrial markets.
Gross profit was $509 million resulting in a gross margin of 47.5% in line with expectations. Gross margin was down 370 basis points year-over-year, mostly driven by temporary factory underutilization as we right-size our inventory levels. Operating expenses of $182 million declined 4% sequentially and year-over-year given our ongoing focus on managing discretionary expenses. We generated $327 million of operating income, translating into an operating margin of 30.5%. We incurred $8 million of other expense and our effective tax rate was 13.2%, driving net income of $276 million and diluted earnings per share of $1.73 exceeding the guidance that we provided during the last earnings call.
Now turning to cash flow, Skyworks business model continues to deliver very strong cash generation. Third fiscal quarter cash flow from operations was $306 million and capital expenditures were $31 million, resulting in free cash flow of $274 million. In fact, for the first three quarters of the fiscal year, we've generated record free cash flow of $1 billion and $350 million and record free cash flow margin of 38%. Also, during fiscal Q3, we paid $99 million in dividends and repaid $500 million of our 2023 notes at maturity.
Now let's move on to our outlook for Q4 of fiscal 2023. We expect to deliver double-digit sequential revenue and earnings per share growth in the September quarter. Specifically, we anticipate revenue between $1.190 billion and $1.240 billion at the midpoint of $1.215 million. Revenue for the quarter is expected to increase 13% sequentially. This outlook considers the seasonal impact from major product launches leveraging our technology leadership, deep customer engagements, and world-class in-house manufacturing capabilities. Gross margin is projected to be in the range of 47% to 48%, reflecting the cyclical impact of lower factory utilization while we are reducing our internal inventories.
We expect operating expenses in the range of $178 million to $182 million, down 6.5% year-over-year at the midpoint as we continue to optimize operating efficiencies while making the necessary investments in technology and product development to further enhance our leadership position in mobile and drive diversification and growth in our broad markets business.
Below the line, we anticipate roughly $8 million in other expense and an effective tax rate of 13.5% to 14%. We expect our diluted share count to be approximately 160 million shares. Accordingly, at the midpoint of the revenue range of $1.215 billion, we intend to deliver diluted earnings per share of $2.10, an increase of 21% sequentially. Lastly, given our conviction and Skyworks long-term strategic outlook and consistent strong cash generation, we announced a 10% increase to our quarterly dividend to $0.68 per share.
And with that, I'll turn the call back over to Liam.
