I would now like to turn the call over to Don Sharon. Mr. Sharon, you may begin.
Thank you, Towanda. Welcome everyone to our fourth quarter conference call. Our earnings release was issued yesterday afternoon on the results of our fourth quarter ended June 30, 2018. We have posted a financial summary presentation to accompany this conference call. The presentation can be found on our Investors Relations website within that events and presentations tab, or if you are listening via the webcast, you can find it in the downloads tab on the webcast portal.
I will begin by making a few remarks on Our sales in the fourth quarter of fiscal year 2018 were down 3% sequentially from the previous quarter, up 15% when compared to the fourth quarter of fiscal year 2017. Very strong growth in our automotive and medical end market verticals helped us achieve the double digit year over year growth in annual sales in fiscal year 2018. As we stated last quarter, our compound annual growth rate or CAGR was approximately 8% over the previous 3 years, and our goal is to sustain this growth rate going forward on an organic and annual basis as we look to grow points from the prior in the fourth quarter, helping to drive the improved overall performance, and we look forward to their continued growth and positive contributions in fiscal year 2019. Partially offsetting the improved operating performance in the fourth quarter were expenses directly associated with our pending acquisition of GES. We remain focused on achieving our mid range goal of 4.5% operating income.
We are disappointed that we did not make progress in fiscal year 2018 toward our long term goal of 12.5 percent ROIC. We still have work to do to achieve this important goal. Margin expansion and capital efficiency will continue to be priorities of focus for us. We continue to leverage We invested $4,400,000 in capital expenditures in the fourth quarter of fiscal year 2018, bringing our fiscal year 2018 total to $26,500,000. We remain focused on doing what's necessary to secure the raw materials in this tight supply market and to maintain the appropriate buffer stock levels to minimize disruptions.
We also have been working diligently to prepare for and respond to the changing landscape as it relates to week in a public hearing on tariffs before the U. S. Trade Representative Committee to voice our concerns and help persuade the U. S. Administration to remove certain electronic components from the proposed list for certain components to which the tariffs went into effect on July 6.
For the tariffs that have taken effect, it will be critical to get accurate information from our suppliers for us to be able to pass to our share owners by purchasing 163,000 shares of our common stock, which brings our total to 44,500,000 and 3,200,000 shares purchased since October 2015 under our board authorized share repurchase program. As we stated on our last call, our work has begun on the implementation of our board approved updated strategic plan. We are committed to optimizing our EMS business by focusing on apple efficiency, margin expansion, and high quality revenue growth. And finally, we are in the process of obtaining the necessary government approvals for our pending acquisition of GES, and we believe it is still on track to close during this quarter, first quarter of fiscal year 2019. Last Friday, July 27th, in anticipation of finalizing the GES acquisition, our primary credit facility was amended and restated to allow for borrowings to $150,000,000 with an option to increase the amount available for borrowing $225,000,000 upon request.
When closed, GES will be the 1st step in our new platform strategy and our plans to continue our development beyond EMS to a multi faceted manufacturing solutions company. Now, I'll turn it over to Mike to discuss our fourth quarter results in more detail. We will then open the call to your questions. Mike?
Thanks, Don. During my comments, I'll be referring to the slide deck Don mentioned, which can be found on our Investor Relations website within the Events and Presentations tab, or if you're listening via webcast, you can find it in the downloads tab on the webcast portal. As shown on Slide 3, our 4th quarter net sales were $276,800,000, which was a 15% increase compared to net sales of 2 $41,300,000 in the prior year fourth quarter. Favorable foreign currency fluctuations accounted for approximately 4% year over year growth. Our net sales mix by vertical market is depicted on Slide 4.
Comparing our net sales by vertical Our automotive vertical was up 20% from a year ago, driven largely by new product introductions, including the continued ramp up of programs in our Romania facility. We did see some softness in compared to a record quarterly sales in our third quarter. From strong demand across the board from our largest existing medical programs. Sequentially, compared to the third quarter, our medical vertical sales were up by double digits Our industrial vertical in Q4 was up by double digits from the prior year, primarily as a result of increases in industrial pumps smart metering and other existing programs, which more than offset the effects of the exit of other certain programs. And our public safety vertical was down 20%, primarily as a result of lower overall demand and programs reaching end of life.
However, when compared sequentially to the third quarter, we are encouraged as public safety was up double digits, largely from an uptick in demand, and a new product introduction. Our gross margin in the 4th quarter reflected on Slide 5 was 8.2%, which was up nicely from 7.5% in the same quarter last year. Gross margin improvement in the current year quarter compared to a year ago included contributions from improvements sales volumes and improved efficiencies. In addition to Romania, the Romania Improvement leverage of higher sales volumes at other units favorable mix and lower costs related to our domestic self insurance health care benefit program also contributed to the gross margin improvement from the prior year fourth quarter. Selling and administrative expenses, slide 6 in the deck were $11,500,000 in the 4th quarter, which were up $1,900,000 or 10 basis points compared to the prior year fourth quarter.
As Don mentioned, selling and administrative costs in Q4 included costs incurred directly related 20 basis points. The remaining increase in S and A cost was largely related to increased employee cost including salary expense and related benefits and incentive compensation costs, which include non cash stock compensation expense. Other income and expense net was expense of $1,100,000 in the fiscal year 2018 fourth quarter, compared to income of 1,100,000 Net foreign currency losses during the current year fourth quarter as a result of unfavorable exchange rate movements were largely worked partially offset by derivative gains, primarily drove the loss to the other income and expense net section of the income statement. The effective tax rate for the current year fourth quarter was an inflated 43%. The significantly higher current quarter rate was largely the result of measurement period adjustments related to tax reform, partly from subsequent guidance released by the IRS during the quarter, as well as a valuation allowance recorded related to state tax credits.
The prior year fourth quarter effective tax rate included favorable adjustments primarily related to state credits and a benefit from the true up of the estimated annual effective tax rate which further lowered the prior year which was significantly impacted by tax reform, accounting for approximately 40% of pretax income. Slide 8 reflects our adjusted net income trend. Net income in the fourth quarter of fiscal year 2018 was $5,800,000 compared to $8,100,000 in the fourth quarter of last year. Non GAAP adjusted net income for the current quarter excluding the impact from the tax reform adjustments was $7,200,000, The last slide of the deck provides a reconciliation of non GAAP metrics to GAAP metrics. Diluted earnings per share was $0.22 in the 4th quarter of this fiscal year compared to $0.30 in the prior year fourth quarter.
When adjusting for tax reform in the current year fourth quarter, Non GAAP adjusted diluted earnings per share was 0.27 dollars. Cash and cash equivalents at June 30, 2018 were $46,400,000. Operating cash flow trends are shown on Slide 11. We had strong cash flow provided by our operations during the current year fourth quarter of $19,300,000 compared to $12,000,000 provided in the fourth quarter of last The operating cash flow provided during the quarter was primarily the result of the earnings during the quarter, plus non cash expenses and a reduction in receivables, which were partially offset by uses of cash from an increase in inventories and a reduction in accounts payable. Slide 12 reflects our capital and depreciation trends.
Capital investments in the 4th quarter totaled $4,400,000, largely related to our investment in new equipment for increased manufacturing capacity and to support new product introductions. Capital investments for the full fiscal year 2018 amounted to $26,500,000, which approximated our depreciation expense for the year and was We also returned capital to our Borrowings on our credit facility at June 30, 2018 were $8,300,000, which were down $8,000,000 from March 31, and down $1,700,000 from June 30, 2017. As of June 30, our short term liquidity available represented as cash and cash equivalents plus the unused amount of our credit facilities totaled $109,000,000. As Don mentioned, our primary credit facility has subsequently been amended and restated for an additional 5 years facility from $50,000,000 to $150,000,000, with an additional $75,000,000 available bond request, The facility is expected to be used for working capital and general corporate purposes, including acquisition This increases our short term liquidity available, which is expected to be partially used to fund the GES acquisition. I would like to conclude by saying With that, I would like to open up today's call to questions from analysts.
Towanda, do we have any analysts with questions in the queue?
Our first question comes from the line of Chase Bassa of AWH Capital. Your line is open.
Good morning guys. Thanks for taking my questions. You had pretty nice sequential and year over year growth in the medical vertical. Can you you give us some additional color on what drove that and the outlook you're thinking for that vertical in 2019?
Yes. We really saw the growth in multiple areas across the the portfolio business we have there, which is, I think, a really positive sign. And we continue to ramp programs relatively new programs such as the programs that we picked up in our acquisition in Indianapolis a couple of years ago. Which had a nice contributing factor to our overall growth. And so pretty widespread.
We're pleased with it some way that's a little bit unexpected, stronger than I think we would have thought going into the quarter and really for the full fiscal year. But we have good momentum and the strength looks to be, as I said, widespread. So we're hoping that it can continue for us going into the new fiscal year.
Okay. And then a little bit of sequential softness in the automotive segment you touched on. Is there an element of seasonality there or what kind of explains that?
Yes, I don't know the seasonality would explain all of that. That's really hard for us to get our heads around what really happened. Between Q3 and Q4. I mean, essentially you have the same programs in production. So yes, seasonality, maybe some softness in the market in some regions.
Contributed to that. We've had this short supply and component shortage situation that's been impacting inventory levels offering levels throughout the supply chain. That also could have had some impact. I think when you look at the numbers, had a hard time explaining why Q3 was so high. So the sequential drop is just as hard to explain, but it's essentially the same book of business play in both quarters.
So we'll see. We'll see how the rest of the calendar year shapes up. And as we go into fiscal year 2019, We expect it to remain pretty strong just given the programs we still have in front of us to ramp, namely new programs. But the current programs that we've got in production will depend really how the overall market does. Correct.
And then regarding the tariff discussion, can you talk a little bit more about your ability to pass on price to customers and just kind of help us understand the sorts of conversations you're having in that regard?
Yes, that's a really good question. And one that's I'm sure being answered by a lot of CEOs and CFOs nowadays in terms of how this ripple effect going to be managed. The first thing I would say, it's going to be an aggravation for everyone, in the value stream. And at the end of the day, I think the pass through concept is going to have to be embraced by everyone or it's going to create disruption and issues. We there's no way that we could absorb tariffs on parts that we buy from China that let's say come into our our U.
S. Manufacturing plants. So we don't have the ability to absorb those costs. So we definitely will have to pass them through to our customers We've already started that dialogue, especially, with several parts on List 2 that could impact us. So we've opened up the dialogue with our customers.
We've given them the specifics at least what we know today The list is never final until it's final. List 1 didn't get finalized till the very end after the hearings. So we expect the same for List 2. But at the end of the day, we have to pass it through. We've been talking to our customers about that.
And it's probably going to end up being a pretty tough negotiation at the end of the day. And as I said, in aggravation, but our plans are to pass it through and we think we have all of the we have all of the room contractually to pass it through that we need. So, that's about the best I could describe that, Chase. I don't know if you have any follow on questions to it.
No, that's helpful. And then on the GES acquisition, is there anything more you can tell us about that acquisition or impact on your fiscal 2019 numbers or anything like that?
Not at this time. I'd just reiterate what we talked about in our press release in terms of the cash allocation or the purchase price of $50,000,000. We're getting down final government approvals. And we hope to get something out to our investors. As soon as we can get a gain in approvals, we need to close the transaction, And we'll be able to add more about what the impact will be to fiscal year 2019 from a top line and most likely EPS
Our next question comes from the line of Mike Rales with Walthausen And Company.
Hi guys. Thanks for taking the question. As we think about some of the new programs that we have ramping throughout fiscal 2019, interested in the component supply situation. Have we gotten any additional insights from our suppliers on when we might be able to expect this to kind of turnover and have this component constrained environment that we're in kind of flip?
Yes, really good, really good question. First of all, on the new programs that we're ramping this year, we've actually been working for over a year on securing supply for those programs And so we feel like we've derisked that part of the ramp up. I mean, it's tight. It's the supply is tight, but we believe that we've got the material lined up that we need to ramp those programs, this summer into the fall timeframe. Most of the component shortages and the manufacturers of those components are telling us, given us an answer today that it sort of depends.
It depends on the demand profile that we'll see in the second half of this calendar year. There's been reports some softening in demand in some end markets that's making more material available. And so we it can improve definitely throughout the year if if the demand truly softens. If it's just a blip, then we get back to some of the growth rates that we as an industry and really the industry overall has seen in say, the first half of twenty eighteen, they're telling us that it could be the end of twenty nineteen before they truly get capacitized to handle, let's say, the new run rates, especially, especially, the manufacturers of some component categories are really for example, the multilayer surrounding capacitor guys are telling us that, that the short supply situation could last 2019 in certain demand profile scenarios. So we'll see.
They're adding new capacity. They've been working hard to add that new capacity. New capacity coming online, for example, in companies like Marotta, by the end of this year. So some in some cases, we'll see some catch up towards the end of the year. The automotive supply is a tougher one in that it's the automotive components are an automotive grade.
And so, our some of our ramp ups, for example, in the automotive space, We pay particular attention to because we depend on that capacity and not the overall capacity, which will include commercial grade.
Got it. All right. Thank you guys for the color. I appreciate it.
I'm showing no further questions at this time. I would now like to turn the call back over to Don for closing remarks.
Thank you, Tiwanda. That brings us to the end of today's call. We appreciate your interest and look forward to speaking with you on our next call. Thank you, and have a great day.
At this time, listeners, you may simply hang up to disconnect from the call. Thank you and have a nice day.
