Thanks, John, and good afternoon. Before I get started, let me say that we anticipate filing our 10-Q for the first quarter of 2017 in the near future. And with that, we will be current with our required SEC filings and be compliant with listing requirements of NASDAQ.
I'll spend a few minutes highlighting Marvell's financial results for the first quarter of '17 before turning the call over to Rick Hill, our Chairman.
For the first quarter of fiscal 2017, we reported revenues of $541 million, which represented a decrease of 12% from the fourth quarter revenues of $616 million and a 25% decline from $724 million in the first quarter of fiscal 2015. Revenue decline in the first quarter of fiscal 2017 relative to the fourth and first quarters of fiscal 2016 was primarily driven by an increased industry demand for HDD products as well as the anticipated decline in revenue resulting from Marvell's exit from the mobile handset business that we announced in September of 2015.
Our first quarter is typically our weaker quarter, where we see revenues decline sequentially and the first quarter of fiscal '17 was no exception. Our storage revenues declined 16% sequentially, mainly due to the continued weakness in the HDD industry TAM. This was partially offset by growth in SSD driven by increased demand.
Our networking business increased 5% sequentially due to improved demand for our networking products, while our mobile and wireless sales declined 29% sequentially due to the continued ramp down of our mobile handset platform business. Please note that the mobile handset revenues in the first quarter of 2017 were $22 million, down from $69 million in the fourth quarter of fiscal 2016 and $65 million in the first quarter of 2016.
Our gross margin percentage for the first quarter of fiscal 2017 increased by 120 basis points from 50.9% of net revenues in Q4 of fiscal '16 to 52.1% in Q1 of '17 and also compares favorably to 51.5% for the first quarter of fiscal year 2016.
Improving gross margin was primarily due to lower percentage of mobile handset revenues. Operating expenses on a GAAP basis for the first quarter of 2017 were $311 million, flat with the fourth quarter of fiscal 2016 and 14% lower compared to $360 million in the first quarter of 2016. Please note that R&D expenses in Q1 fiscal '17 were $241 million or 45% of revenues compared to $240 million or 39% of net revenues in Q4 and $280 million or 39% of net revenues in Q1 fiscal 2016. The $39 million decrease in R&D spending in Q1 '17 compared to Q1 2016 was largely due to restructuring of the mobile handset business, which we announced in September that has now been completed. I'll talk more about the restructuring in a few minutes.
Please note the small increase in R&D spending in Q1 '17 relative to Q4 was largely due to increased payroll costs related to merit increases effective April 1, increased payroll taxes starting in new calendar year as well as savings from the holiday shutdown in December, which didn't occur in our first quarter of fiscal 2017.
SG&A expenses on the other hand were $69 million or 13% of net revenues in Q1 2017 compared to $72 million or 12% of net revenues in Q4 2016 and $80 million or 11% of net revenues in Q1 '16. Please note that operating expenses on a GAAP as well as a non-GAAP basis for the first quarter of fiscal 2017 and the fourth quarter of fiscal 2016 includes $17 million and $11 million respectively of accounting and legal fees related to the audit committee investigation and related shareholder litigation, investigation by the SEC and the United States Attorney's Office, as well as other professional fees.
In summary, in Q1 2017, we reported a GAAP net loss of $23 million or $0.04 per diluted share compared to a GAAP net income of $4 million or $0.01 per share diluted for the fourth quarter of fiscal '16 and a GAAP net income of $14 million or $0.03 per share diluted for the first quarter of fiscal 2016. We were essentially breakeven on a GAAP basis in Q1, if you exclude the $4 million restructuring charge coupled with the $17 million of increased legal and accounting fees mentioned earlier.
Now let me spend a few minutes reviewing our financial performance on a non-GAAP basis. On a non-GAAP basis, net income for the first quarter of fiscal 2017 was $7 million or $0.01 per share diluted, which includes adjustments of approximately $29 million, $25 million of which is related to stock-based compensation and $4 million related to restructuring, $1 million of which was related to the mobile handset business, which was completed in Q1 of fiscal 2017.
Now let me comment for a few minutes on the mobile handset platform restructuring, which we announced in September last year. We ended up eliminating 950 positions in the mobile handset business unit, which is 150 less than what's expected as we decided to retain more employees and equipment to report remaining business than was anticipated. The end result of the restructuring is that we estimate the annual cost savings of approximately $130 million, including employee-related facilities and equipment cost, which you are now seeing realized in our Q1 R&D spending levels. This compares to the original estimated annual savings on the low end of the range of $155 million or $25 million less. As I mentioned earlier, our total R&D spending in Q1 of fiscal '17 was $39 million less than in Q1 '16, which was largely due to the restructuring of our mobile handset business. Please note, more work is needed in the near term in bringing our operating expense levels in line with our revenues and long-term strategy.
Our non-GAAP gross margin for the first quarter of '17 improved slightly to 52.5% from 51.9% in the fourth quarter, largely due to favorable product mix relating to higher networking sales and lower volume of mobile handset products. Non-GAAP operating expenses in Q1 '17 came in at $280 million compared to $267 million in the fourth quarter, a 5% increase, and $307 million in the first quarter of fiscal '16, a 9% decline. As I mentioned previously, our GAAP as well as our non-GAAP operating expenses for the first and fourth quarters of fiscal 2017 and '16 includes $17 million and $11 million, respectively, of increased legal and accounting fees, which are included in G&A.
In Q4, we had the benefit of a holiday shutdown resulted in lower employee cost relative to Q1, which was offset by increased personnel costs with the annual merit increase effective April 1 and higher payroll tax in the new calendar year. The overall decrease in Q1 '17 spending compared to Q1 '16 is primarily due to lower R&D spending as a result of a shutdown of the mobile platform business. The end result is that in Q1 fiscal '17, we reported non-GAAP net income of $7 million or $0.01 per diluted share compared to $0.11 in Q4 '16 and $0.13 per diluted share in Q1 fiscal 2016.
Please note, if you exclude the impact of the added legal accounting fees, which are included in our non-GAAP operating expenses of $17 million in Q4 of '17, $11 million in Q4 '16, our adjusted non-GAAP EPS would have been $0.05 per share in Q1 '17 versus $0.01 per share as reported compared to $0.13 as adjusted in Q4 '16 versus $0.11 as reported and $0.13 per share in Q1 fiscal '16. Net cash provided from operations for the first quarter was negative $610 million, which reflects the $750 million payment related to Carnegie Mellon University litigation settlement or a plus $140 million on adjusted basis compared to $53 million in the fourth quarter of fiscal 2015 and $59 million in the first quarter of fiscal 2016.
With that, I would like to turn the call over to Chairman Rick Hill to provide additional color on Q1 operating results and our Q2 outlook.
