Thank you, Revathi. Please turn to Slide 3 for our Q4 income statement summary. Our fourth quarter revenue was $6.2 billion, down 3% versus a year ago and towards the low end of our guidance range. On all 4 of our business groups, we're within their revenue guidance ranges, albeit some on the lower end. Our Q4 adjusted operating income was $204 million, which was within our guidance range and up 2% year-over-year. Our adjusted net income was $141 million, resulting in adjusted earnings per diluted share of $0.27, which was within our guidance range of $0.25 to $0.28.
Fourth quarter GAAP net loss of $64 million was lower than our adjusted net income due to adjustments for stock-based compensation, intangible amortization and several of nonrecurring charges totaling $206 million or $0.39 per share. This resulted in a fourth quarter GAAP EPS loss of $0.12. We streamlined our investment portfolio, which resulted in a noncash impairment charge of $119 million. We also continued to take targeted actions to optimize our business, most notably within our CTG business where we have been rationalizing and pruning underperforming accounts as well as eliminating certain noncore activities as we reposition it to align with go-forward company strategies. This resulted in restructuring and impairment charges of $37 million, of which $19 million were noncash in nature.
Now please turn to Slide 4 for quarterly financial highlights. Year-over-year, our adjusted gross profit decreased to $408 million, while our adjusted gross margin declined 10 basis points to 6.6%. The gross margin pressure is reflective of various business mix shifts, which were most notable inside HRS due to lower automotive revenue. Additionally, we experienced some transitory operational inefficiencies as we ramped new programs within our CEC business. Operating with a stronger cost discipline has been a big focus the past 2 quarters, and the results can be seen in our fourth quarter adjusted SG&A expense, which declined by 11% year-over-year to $204 million. We remain focused on driving further productivity improvements and refining our cost structure while balancing investments into our design and engineering capability with the objective of delivering sustainable operating earnings leverage. Our quarterly adjusted operating income came in at $204 million, which is up 2% from the prior year and reflects a year-over-year margin expansion of 20 basis points to 3.3%.
Please turn to Slide 5 for our fourth quarter business group performance. I'll begin with our most profitable business, High Reliability Solutions, or HRS, which is comprised of automotive and health solutions. Consistent with our guidance, total HRS revenue was $1.2 billion, down 4% year-over-year. HRS' adjusted operating margin was 7.7% versus 7.8% in Q4 of the prior year. Our automotive business continued to be impacted by market softness, most notably in China, which has directly impacted our largest automotive customers, resulting in Q4 revenues declining 12% from last year. For fiscal 2019, automotive revenue declined 5% to $2.8 billion. Despite the macro headwinds we have faced in 2019, we remain pleased with our global scale, diversified products and services and domain expertise, all of which led us to securing our single largest design contract for a Level 4 autonomous compute module this past year, which also included the associated manufacturing contracts.
We believe we are well positioned on the secular trends of electrification, increasing connectivity and autonomous features. And with our recent bookings in North America, Europe and Asia, we are confident that customers recognize the value we bring across design and manufacturing in these growth areas. Fiscal 2019 marked the year we began to show meaningful growth in health solutions. Its Q4 revenue was up 10% and has consistently grown revenue year-over-year every quarter in fiscal 2019 and ended the year at a record $2 billion. We have benefited from our prior year investments in design, engineering and automation that led to new customers and programs in drug delivery, diagnostics and medical devices as we captured record-level bookings in this business, which positions us well as we move forward.
Next, revenue from our Industrial and Emerging Industries, or IEI business, was $1.5 billion, down 8% year-over-year and was at the lower end of our expectations for flat to down high single digits. The Q4 revenue decline was driven by anticipated weakness in both semiconductor capital equipment, which was significantly down; and energy. IEI is structurally positioned for growth as it continues to capture strong bookings from some of the world's largest diversified industrial companies. Despite the lowered revenue, IEI grew its adjusted operating profits by 8% to $73 million; and its adjusted operating margin was a strong 4.8%, up substantially from 4.1% in Q4 of the prior year. IEI continues to benefit from solid execution on various new businesses that it is ramping and greater levels of design-led engagements.
For Communications and Enterprise Compute, or CEC, revenue was $2 billion, up 6% year-over-year, making this the third consecutive quarter of year-over-year revenue growth. However, this performance fell on the lower end of expectations of 5% to 15% year-over-year revenue growth. CEC's adjusted operating margin was also below our expectations coming in at 2.2%, down 20 basis points from the prior year. Our Q4 revenue growth was driven from our increased participation in both hyperscale and edge computing programs and the 4G and 5G network infrastructure build-out. However, we experienced weaker-than-forecasted demand from several of our customers in networking, which pushed us to the lower end of our expectations.
In our Consumer Technologies Group, or CTG business, revenue was $1.5 billion, down 7% year-over-year and within our expectation for the group to be flat to down high single digits. CTG's adjusted operating margin was 1.6%. We continue to reposition our CTG portfolio and rationalize and prune underperforming accounts as we continue to manage the mix of this business. We will continue to be more selective with our CTG customers and product categories. In addition, as we continue our near-term portfolio rationalization during fiscal 2020, we expect CTG's profitability to remain under pressure.
Turning to Slide 6. Let us review our cash flow generation. Fiscal 2019 saw a completely different cash flow execution between the first half and the second half of the year. As we highlighted back in our Q2 earnings, we had expected a solid return to positive adjusted operating cash flow and free cash flow generation in the back half of this fiscal year as our earnings improved and capital intensity lessened. This quarter, we generated $246 million in adjusted cash flow from operations and $120 million in free cash flow. This brought our second half free cash flow generation to be $493 million higher than the first half. This resulted in a second half free cash flow conversion of 77%. Our Q4 free cash flow conversion was 85%, which is improving and is returning towards historical levels.
Our capital expenditures totaled $126 million for the quarter. We continued to invest in the CapEx necessary to support the underlying higher-margin, long-term programs in our IEI and HRS business. Our fiscal 2019 net CapEx totaled $631 million and reflected sizable investments into the regional build-out of our India capability and capacity. As we look forward into 2020, we expect that our CapEx will more closely align with our annual depreciation levels, thereby providing improvement to our free cash flow. It is our goal to consistently be generating positive adjusted operating cash flow and free cash flow as we move forward. We remain committed to returning greater than 50% of our free cash flow to shareholders via share repurchases. During our fourth quarter, we repurchased roughly 6.6 million shares for $65 million.
Turning now to Slide 7 to review our balanced capital structure. We continue to operate with a balanced capital structure with staggered debt maturities and with a relatively low average cost of debt. We ended the year with $1.7 billion of cash and access to liquidity that supports our long-term business growth objectives.
Please turn to Slide 8 for our first quarter fiscal 2020 guidance. Revenue is expected to be in the range of $6.1 billion to $6.5 billion based on the following business group year-over-year revenue expectations. For HRS, revenue is expected to be flat to up low single digits as we anticipate the auto demand environment to remain muted and we continue to see solid demand growth in our health solutions business.
We expect IEI to be up mid- to high single digits as we see several new programs ramping in home and lifestyles and we continue to experience weak demand in our semiconductor capital equipment. CEC's revenue is expected to be flat to up mid-single digits with sustained strength in our cloud data centers solutions business and improvement in 4G and 5G spend, offset by legacy networking demand erosion. And for CTG, we expect revenue to be down 15% to 25%, reflecting the effects of our consumer portfolio rationalization and a softer demand from certain consumer customers.
Our adjusted operating income is expected to be in the range of $195 million to $225 million. Interest and other expense is estimated to be approximately $50 million to $55 million. We expect our tax rate in the first quarter to remain in the midrange of 10% to 15%. Adjusted EPS guidance is for a range of $0.25 to $0.29 per share based on weighted average shares outstanding of 517 million. GAAP EPS is expected to be in the range of $0.18 to $0.22 after reflecting the impacts of stock-based compensation expense and intangible amortization. We remain focused on improving the way we operate our well-balanced and diversified portfolio of businesses and continue to do more to propel disciplined and consistent execution to drive greater productivity, margin leverage and free cash flow in our business.
With that, let me turn it back over to Revathi for some closing comments before we open the call to Q&A.
