good morning, everyone. I'm very pleased with our operating results for the 4th quarter and the strong finish to a record setting fiscal year 2021. Our team remains laser focused on fulfilling the commitments made to our customers as we work through the ongoing challenges, powered by the pandemic and the global parts shortage. Despite the headwinds, we delivered strong top line growth, excellent margin expansion And impressive earnings growth with operating income exceeding our goal of 4.5% for the 4th consecutive quarter And adjusted Q4 EPS increasing 71% over the same period last year. For the full fiscal year, 2021 was a record year for our company with many Financial metrics, including net sales, margin rates, earnings, cash flow from operating activities And return on invested capital reaching all time high.
Our team has demonstrated out these unprecedented times And we are well positioned to carry the momentum from 2021 into fiscal year 2022. As a result of the ongoing semiconductor shortage, a portion of our shippable backlog continues to shift out ahead of which will likely result in 2 very different halves in fiscal year 2022. Our full year guidance, which Janna will discuss in a few moments, contemplates this publication as we expect the material steadily catch up with customer demand throughout the first half of fiscal year twenty twenty two, thus enabling us to shift the majority of the surplus backlog In the second half of the fiscal year and into fiscal year 2023, we expect that catching up on the backlog combined with strong organic growth from new and existing programs will provide significant year over year growth. Beyond the record setting results for fiscal year 2021 and the bullish outlook for fiscal year 2022, We have never lost sight of the fact that the health and safety of our employees remains our number one priority. Our protocols have minimized disruptions to the business and allowed us to maintain excellent customer support as reflected in our top line growth during this period of uncertainty.
Net sales in Q4 increased 15% compared to the same period last year. This was a stronger finish to fiscal 2021 than what we discussed 90 days ago on our last earnings call. The growth was concentrated in our automotive and industrial vertical markets. Automotive was up 92% in Q4 as compared to a year ago as the industry returns to more normalized levels of volume after the shutdown a year ago due to the pandemic. The business continues to benefit from 2 industry wide megatrends.
1st, the demand for vehicles is red high As communities reopen from the pandemic and consumers, and you have cash in their pockets, leave their homes and take to the road to reengage with society. OEMs have been responding to this surge in demand by ramping up production to keep pace and most agree there is not a foreseeable hand in sight. The second Megatron is the continued growth in electronic content per vehicle. Cars and trucks are being designed with advanced technologies and expanded operating systems. Electronic braking and redundant systems for self driving cars.
These are all good examples of this mega call and represent continued growth opportunities for our business. Moreover, the applications and architecture for these systems are largely the same for both electric vehicles, Vehicles driven by internal combustion engines and the study of production standards in the automotive industry for these systems align well With our core manufacturing competency, us in making Kimball Electronics a supplier choice. There is inherent stickiness in these long term relationships when we win a program and it produces an ongoing stream of orders that allows for operating efficiency. You can see this dynamic in our customer base, which gives us confidence in the growth potential of this vertical market in the years to come. Sales Sales in the industrial vertical increased 17% in the 4th quarter compared to the same period last year, with the strength resulting from automation test and inspection sales and higher end climate control products.
We expect this strength to continue in fiscal year 2022. The medical vertical market was down 31% in Q4 as a result of strong prior year sales related to the COVID-nineteen pandemic and lower levels of elective procedures this year. We are starting to see this trend reverse as more of the population is call. And physicians, offices and hospitals are able to resume elective procedures and activities. Longer term, we believe the mega Trends in the healthcare industry such as the world's aging population, increasing access and affordability to care, Decreasing device sizes and connected drug delivery systems are an excellent setup for future growth in this vertical market.
And finally, sales in Public Safety were $10,800,000 down 10% from the prior year. This is yet another temporary impact of the COVID-nineteen pandemic As the reduction in sales is primarily related to commercial and hotel smart locking systems, we anticipate this market will return to normal over time as people resume travel. I am so proud of our team and their efforts to deal with the challenges throughout the year. We have been working diligently to find solutions to minimize or even negate the global part shortage. This is a great example Our strong company culture is creating quality for life.
I'll now turn the call over to Jana to
Thanks, Don, and good morning, everyone. Net sales in the 4th quarter were $329,100,000 a 15% increase compared to $286,200,000 in Q4 last year. Foreign exchange rates favorably impacted sales by 3% in the Q4 of 2021. Our gross margin rate in Q4 was 9.7%, a 240 basis point increase from the Q4 of last year, driven by improved operating execution, higher sales volumes in the automotive vertical, as Don highlighted, and favorable foreign exchange. Adjusted selling and administrative expenses were $13,800,000 in the 4th quarter, up 3,700,000 of 0.7% of net sales compared to the Q4 last year.
This increase was primarily driven by salary and payroll related costs and higher profit sharing bonuses. As a reminder, adjusted selling and administrative expenses call. Adjusted operating income for the 4th quarter was $18,000,000 or 5.5 percent of net sales. This represents an improvement of $7,200,000 or 1.7 percent of net sales when compared to the same period last year. The increase was driven by the higher gross profit that I just mentioned, partially offset by the change and selling and administrative expenses.
Other income and expense was income of $400,000 in the 4th quarter, which compares to expense of $2,700,000 in Q4 fiscal 2020. The income this year resulting from gains on SERP investments and favorable FX, partially offset by net interest expense and all other expenses. The effective tax rate in Q4 was 17.6%. The low effective tax rate in Q4 was primarily driven by a favorable mix of earnings and our various tax jurisdictions. Adjusted net income in the Q4 of fiscal year 2021 was $14,700,000 or $0.58 per diluted share compared to adjusted net income in Q4 last year of $8,500,000 or $0.34 per diluted share.
As Don noted, this represents A 71% improvement in EPS year over year. Now Turning to the balance sheet. Cash and cash equivalents at June 30, 2021 were 106 $400,000 Cash flow provided by operating activities during Q4 was 26 point $3,000,000 our 5th consecutive quarter of $20,000,000 plus Cash Conversion days for the quarter ended June 30, 2021 were 64 days, representing a 17 day improvement from Q4 2020 and a 2 day improvement from last quarter. Compared to Q4 20 20, we experienced improvement in contract asset days and production days supply on hand. Capital investments in the first quarter were $15,900,000 largely to support the launch and ramp up of new programs and to support our facility expansions in Thailand and Mexico.
We continue to study our capacity needs to support growth plan. As highlighted on our Q3 call, we anticipate higher levels of CapEx to support the expansions of our operations in Thailand and Mexico over the course of fiscal year 2022. Both expansions add much needed capacity to support the forecasted growth from both existing and future customers and demonstrate our strong organic growth opportunities. Borrowings on our credit facilities at June 30, 20 21 were $66,000,000 which is down from $118,000,000 a year ago. Our short term liquidity available represented as cash and cash equivalents plus the unused amount of our credit facilities totaled $207,000,000 at June 30, 2021.
There were no shares repurchased in the Q4 of fiscal year 20 21. Since October of 2015, under our board authorized share repurchase program, A total of $79,700,000 was returned to shareholders by purchasing 5,300,000 shares of common stock. As Don highlighted, the full year fiscal 2021 was record setting for our company with a number of financial metrics achieving all time high. Net sales were $1,292,000,000 an 8% increase over the prior year. Adjusted operating income was 5.2 percent of net sales, a 180 basis point improvement from fiscal 2020.
Adjusted net income totaled $56,400,000 compared to $28,000,000 last year. And adjusted EPS was $2.23 more than double fiscal 2020. Included in the results this year was a favorable impact from foreign rate movement, which resides in other income and expense. Excluding this impact of $0.17 The adjusted net results for fiscal 2021 of $2.06 was still well above the $1.10 we reported a year ago. We generated $130,000,000 of cash from operating activities and our return on invested capital reached 13.1%, best in our history.
Now turning to fiscal 2022. For the first time in our company history, we are providing guidance for the full fiscal year. We estimate net sales will be in the range of $1,400,000,000 to $1,500,000,000 an 8% to 16% increase over fiscal 2021. Operating income margin is expected to be 4.5% to 5% of net sales. And finally, we expect to invest $60,000,000 to $70,000,000 in capital expenditures in the fiscal year.
I'll now turn the call back over to Don.
Thanks, Tiana. Before we open the lines for questions, I'd like to take a moment to Reiterate how proud I am of our team. We posted excellent operating results for the 4th quarter despite meaningful headwinds We finished our record year with strength. We are also well positioned to carry the momentum in the fiscal year 2022 by guiding for growth. The company is in a solid position and we are committed to build success in the future.
With that, I would like to open the lines for questions. Operator, do we have any analysts with questions in the queue?
The first question comes from the line of Anna Salstrom with Sidoti.
Hi, everyone. Can you hear me?
Yes, we can, Anna.
Thank you for taking my question, and congratulations on a strong quarter year despite the challenging environment. Thank you. I just follow-up the call. You talked about the auto industry and then and I assume you talked about the industrial You saw strength in the GS and the climate controls there. Is that correct?
Yes, that's correct.
And then what do you see in terms of the smart metering over in Europe? I I would assume that the climate control is driven by the COVID, the people going back to Offices and hotel and everything opening up, you look to move over there, because controls sort of might be when that elevation About if that maybe normalizes and the smart metering in Europe is coming on board again? Or how should we think about the growth in industrials?
Yes. The smart metering business in Europe is still being held back by the pandemic. And so It will require quite a bit of change yet in terms of the environment there in Europe And being able to have access for installation purposes of those smart meters. So we're anxiously watching that Business and hoping for its return, but it's absolutely related to getting this pandemic behind us Before we would see, let's say, pre pandemic run rates. The rest of our business in the industrial vertical remains is healthy.
Climate control in a number of areas remains healthy. And as you said, automation test And measurement, Q4 is their strongest quarter, and they had a strong quarter in Q4 this year. We expect the industrial vertical to continue to be strong for us as we go forward.
Okay. And what do you see in In terms of the medical, the electives there, that's sort of muting that growth there. How was that trending throughout the quarter?
We're seeing signs of improvement and that the trend there is improving in terms of Those products we build to support those elective procedures and surgeries. So we're optimistic that that trend will continue. Of course, with the new Delta variant and the sort of concerns around that, we're hoping that What we've seen in the past quarter in terms of a positive trend doesn't get reversed here this quarter, but so far so good. We're In a nice positive trend in terms of the return of that business, it's going to take some time we believe, but it's definitely trending upward.
Okay. Thank you. And also, I might have missed it on the call, but the SG and A for the quarter was a bit Elevator, I think it was due to salaries and performance bonuses. How should we think about that going forward?
Yes, you're right. That's exactly what caused that number to move up. I think, Obviously, with the guidance, the full year guidance that we've provided, the 4 5% to 5% operating income margin, that's really where I'd like you to focus. Obviously, that requires gross margin It should be higher than SG and A by that range. And so rather than trying to give you an SG and A number and a gross margin number, I'd want you to just focus on that range of operating income margin between 4.5% and 5%.
Okay. Thank you. That's helpful. You've been able to manage your working capital Well, I'm building up quite some nice cash and seems like you're going to continue to generate good cash. What are you thinking about the use of cash going forward?
Well, 1st and foremost, supporting our organic growth. As we announced In previous calls and reiterated today, the expansions, much needed capacity expansions in Land in Mexico, funding those types of expansions to support what we see as a very strong organic growth funnel of new opportunities. And just to comment on the working capital, I'm just so pleased with the results This past year, improving our cash conversion cycle. I think structurally now with these improvements this year. We're about where we expect the business to run.
For various reasons that we talked about In previous quarters, we had higher inventory levels, for example, and we explained why. But with the work we did this past year, I think Fund. Structurally, with the cash conversion cycle and cash conversion days being at 64, Structurally, that's where we expect the business to run. So going forward, the working capital in dollars will increase commensurate With the top line growth, so that's a funding need as well when we think about growth going forward. It's not just CapEx.
It's having that working capital Grow with that top line and that absolutely is our number one priority for capital allocation.
The next question comes from the line of Mike Morris with Walthausenhausen and Company.
Hey, good morning, Don. Good morning, Janet. Thanks for taking the question.
Good morning, Mike.
Good morning, Mike.
So I'll echo the congratulations. Phenomenal work on the strong quarter and the great year, especially with everything that you and the rest of the The industry has had to deal with and really great numbers that you folks have put up. And I kind of want to start on understanding just How you guys did that, certainly dealing with high supply chains is in your guys' DNA, and that's what you do. Thinking about the last quarter, There were concerns about the commitments on the supply chain. It seems like you navigated through that without too many of that or those happening.
Where you were sitting today, has the outlook materially changed at all from what you were seeing last quarter, either positively or negatively?
In the whole, let's say, semiconductor shortage area, we've seen areas of improvement. We've actually seen some areas that have gotten worse. So it's a bit of a mixed bag. I think, as I mentioned in the last call, we're fortunate in that many of especially in our automotive business, Many of the vehicles that we have content on through our customers are priority vehicles, vehicles that are getting priority With the chip shortages, that helps. But it's been impactful.
And as we mentioned, we have a fair amount of shippable backlog that continues to move out ahead of us. And we're Trying to manage that the best we can. In other words, organizing ourselves and planning ourselves around the gate, the gating item. We spend a lot of time our operations team spend a lot of time trying to get that right. That's a lot of extra work, but it helps minimize the disruption of the shortages.
It's hard to put an exact number on the shippable backlog that's rolling out ahead of us. But when you think about our guidance For the full year in that $1,400,000,000 to $1,500,000,000 range, as you know, Mike, we've had a target of Growing the business around 8% organically. So that's sort of the low end of our range. The high end really contemplates Catching up some of that surplus backlog, so it gives you kind of an idea of how much that shippable backlog, How much of dollars that's moving out ahead of us. So that's something we really want to watch carefully, have a good plan to catch up on so that We can continue to support our customers the way we have been and, yes, get them back to the inventory levels they need to execute their plans as well.
So we're not out of it. The first half of fiscal year twenty twenty two, we believe, is going to continue to be challenging With these part shortages, and we're going to have to do what we did last quarter for a couple more quarters before we could expect that, yes, the Supply would catch up with demand. That's why we're talking about 'twenty two being 2 different halves for us. And we're optimistic it will improve. Most analysts are predicting that the situation will just continue to improve over the next couple quarters.
And we're hopeful for that because that would really allow us to again focus our energies
That's really helpful. And in your response there, you kind of touched on guidance, Which I'd like to turn to, as a shareholder, really appreciate the business being at a point where you guys are comfortable going out and putting These numbers out here, I think that really speaks as a testament to the improvements that you guys have made and where the business is at today. Thinking about the targets that you folks have laid out, historically, when you've talked about that top line growth 8% and an operating margin target at around 4.5%. You mentioned it in your response just before that those are now kind of the low end of the guidance that you've put out. So my question is, as we think about longer term targets and the outlook for the business, has that 4.5% operating margin target that you guys talked about call.
Should we now think about a long term target? Is that 4.5% to 5%? Or is there an opportunity for you guys revisit and talk about longer term targets beyond that. Just how are you thinking about it as a whole now?
We're definitely staying on the operating income target. As you know, we put that target out there for ourselves, must At least a few years ago, quite a while ago at least, and we pushed ourselves hard to get there and to get there on a more consistent basis with real improvements in our operations, better operating leverage, better use of our footprint, Really focusing on the things we have to do to truly make those improvements that we could then predict going forward. Our teams have done a great job. And despite all the headwinds we talked about, the pandemic and the shortages, we believe that we've made Sustainable improvements in our factories and in our supply chain activities. Now we're still Battling some of those things that other manufacturing companies are battling, whether it's worker shortages, increases And wages and salaries and other inflationary costs around raw material, but we believe we've made improvements that are sustainable.
We're going to work our way through those issues, and we think it's time to raise our expectations from that 4.5% target that we put out there those years ago and be in that landing area, if you will, between 4.5 5 on a consistent basis. We were just really tickled this year to be able to finish the full year with all 4 quarters above 4.5. And that we had to prove that to ourselves that we think that those improvements are then sustainable going forward, but we believe they are.
I will now turn it back over to Don Charian for closing remarks.
Thank you. 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.
This concludes today's presentation. You may now disconnect.
