EBITDA (a non-GAAP measure), which represents earnings before net interest expense, income tax, depreciation and amortization, in the fourth quarter 2018 was $70.5 million, or 22.4 percent of revenue, compared to $47.0 million, or 17.5 percent of revenue, in the fourth quarter 2017 and $72.0 million, or 22.4 percent of revenue in the third quarter 2018. For a reconciliation of GAAP net income to EBITDA, see the table near the end of this release for further details.
For fourth quarter 2018, net cash provided by operating activities was $61.6 million. Net cash flow was a positive $90.7 million, including $47.4 million of additional long-term debt to fund a previously committed shareholder equity increase in the Company's Chengdu corporate entity. Free cash flow (a non-GAAP measure) was $46.3 million, which includes $15.3 million of capital expenditures.
As of December 31, 2018, the Company had approximately $249 million in cash, cash equivalents and short-term investments, long-term debt (including the current portion) totaled approximately $214 million, and working capital was approximately $481 million.
The results announced today are preliminary and unaudited, as they are subject to the Company finalizing its closing procedures and customary quarterly and year-end review by the Company's independent registered public accounting firm. As such, these results are subject to revision until the Company files its Form 10-K for the year ending December 31, 2018.
Dr. Lu further commented, “We expect revenue in the first quarter of 2019 to be approximately $302 million, plus or minus 2.5 percent. At the mid-point, this represents growth of 10 percent over the prior year period and down approximately 4 percent sequentially, which is slightly better than typical seasonality. We expect GAAP gross margin to be 36.0 percent, plus or minus 1 percent. Non-GAAP operating expenses, which are GAAP operating expenses adjusted for amortization of acquisition-related intangible assets, are expected to be approximately 21.5 percent of revenue, plus or minus 1 percent. We expect net interest expense to be approximately $2.0 million. Our income tax rate is expected to be 25.0 percent, plus or minus 3 percent, and shares used to calculate diluted EPS for the first quarter are anticipated to be approximately 51.2 million.”
Purchase accounting adjustments related to amortization of acquisition-related intangible assets of $3.7 million, after tax, for Pericom and previous acquisitions are not included in these non-GAAP estimates.
