Medtronic Stock Analysis

Like my Coca-Cola stock analysis I was surprised when I looked back through my stock analysis archives that I had never posted about Medtronic (MDT).  I had actually gone through the full analysis back in June of this year but couldn't find my post so I"m assuming I ended up getting busy with last minute wedding stuff. Medtronic is another one of the companies that I would love to own a piece of but the price just hasn't been there when my capital was available.  Medtronic closed trading on Monday, December 10th at $42.60.

Company Background:

Medtronic, Inc. manufactures and sells device-based medical therapies worldwide. It provides products for the diagnosis, treatment, and management of heart rhythm disorders and heart failure, including implantable cardiac pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy devices, arctic front cardiac cryoablation catheters, arctic front cardiac cryoablation catheters, and patient management tools. The company also offers cardio vascular products, such as percutaneous coronary intervention device, which is used for the treatment of patients with coronary artery disease; renal denervation for the treatment of chronic uncontrolled hypertension; endovascular stent grafts to treat abdomen and thoracic regions of the aorta; peripheral vascular intervention that encompasses various procedures to treat patients with peripheral vascular disease; surgical valve replacement and repair products for damaged or diseased heart valves; transcatheter heart valves; a line of blood-handling products used in arrested heart surgeries; positioning and stabilization technologies that assist physicians performing beating heart surgery; and surgical ablation system, which allows cardiac surgeons to create ablation lines during cardiac surgery. In addition, it provides medical devices and implants that are used in the treatment of the spine and musculoskeletal system comprising thoracolumbar, cervical, and biologics products; neurostimulators for chronic pain, implantable drug delivery systems, and deep brain stimulation systems, as well as urology, fecal, and gastroenterology devices; and integrated diabetes management solutions. Further, the company offers products and therapies to treat diseases and conditions of the ear, nose, and throat, as well as certain neurological disorders; and image-guided surgery and intra-operative imaging systems.

DCF Valuation:

Analysts expect Medtronic to grow earnings 5.21% per year for the next five years and I've assumed they can continue to grow at 3.50% per year thereafter, right around the long term inflation rate. Running these numbers through a two stage DCF analysis with a 10% discount rate yields a fair value price of $59.83. This means that at $42.60 the shares are undervalued by 28.8%.

Graham Number:

Over the last 12 months, Medtronic's EPS were $3.29 and it's current book value per share is $16.98. The Graham Number is calculated to be $35.45, which means it is currently overvalued by 20.2%.

Average High Dividend Yield:

Medtronic's average high dividend yield for the past 5 years is 2.50% and for the past 10 years is 1.75%. This gives target prices of $41.53 and $59.57 respectively based on the current annual dividend of $1.04. These are overvalued by 2.6% and undervalued by 28.5%, respectively.  I think the average high yield is going to be creeping higher over the next few years so I'll use the higher 5 year average price target in the fair value calculations.

 Average Low PE Ratio:

Medtronic's average low PE ratio for the past 5 years is 13.80 and for the past 10 years is 19.77.   This corresponds to a price per share of $44.43 and $63.66 respectively based off the analyst estimate of $3.65 per share for the fiscal year ending in April 2013.  The 5 year and 10 year low PE price targets are undervalued by 4.1% and 33.1%, respectively.  The 10 year low PE ratio is skewed to very high levels thanks to the overvaluation of the shares in the early 2000's.  In 2001 the low PE ratio for MDT shares was 50.  Since then the PE ratio has been slowly moving down to more realistic levels so I'll use the 5 year low PE ratio in my fair value calculations, although to since 2009 the average low PE ratio is even lower at 11.38.

Average Low P/S Ratio:

Medtronic's average low PS ratio for the past 5 years is 2.42 and for the past 10 years is 3.84. This corresponds to a price per share of $38.51 and $61.20 respectively based off the analyst estimate for revenue growth from FY 2012 to FY 2013.  Their current PS ratio is 2.64 over the last 12 months.  The 5 year and 10 year low PS price targets are overvalued by 10.6% and undervalued by 30.4%.  Like the high dividend yield and low PE ratio valuations I think the 5 year average will be more typical going forward than the 10 year averages thanks to the overvaluation in the early 2000's.

Dividend Discount Model:

For the DDM, I assumed that Medtronic will be able to grow dividends for the next 5 years at the minimum of 15% or the lowest of the 1, 3, 5 or 10 year growth rates. In this case that would be 7.78% from the 1 year growth rate.  After that I assumed they can continue to raise dividends for the next 5 years at 75% of 7.78%, or 5.83%, and by 3.50% in perpetuity.  The dividend growth rates are based off fiscal year payouts and don't necessarily correspond to quarter over quarter increases.  To calculate the value I used a discount rate of 10%. Based on this, Medtronic is worth $20.33 meaning it's overvalued by 109.5%.

PE Ratios:

Medtronic's trailing PE is 12.95 and it's forward PE is 11.04.  The PE3 based on the average earnings for the last 3 years is 14.41. I like to see the PE3 be less than 15 which Medtronic is currently under.  Compared to it's industry, MDT seems to be undervalued versus JNJ (23.12) and BDX (13.86).  Against the industry as a whole, MDT is undervalued with the industry carrying a PE ratio of 20.26.  All industry comparisons are on a TTM EPS basis.  Medtronic's PEG for the next 5 years is currently at 2.24 while Johnson & Johnson is at 2.26 and Beckton Dickinson is 2.03.  A low PEG ratio is better because it means that you're paying less for the growth of the company.  Medtronic's PEG is on par with JNJ's but well above BDX.


Medtronic's gross margin for FY 2011 and FY 2012 were 81.6% and 79.6% respectively. They have averaged a 80.2% gross profit margin since 2001 with a low of 79.00% in FY 2007. Their net income margin for the same years were 19.4% and 22.3%.  Since 2001 their net income margin has averaged 19.4% with a low of 14.9% in FY 2009.  I typically like to see gross margins greater than 60% and at least higher than 40% with net income margins being 10% and at least 7%.  Medtronic obliterates both of these criteria.  Since each industry allows for different margins it's prudent to see how MDT compares to their industry.  For FY 2012 Medtronic captured 115.4% of the gross margin for the industry and 143.7% of the net income margin.  This is very promising because it means that their operations are more efficient and that they have some pricing power.  It also means that for every $1 in revenue they are able to turn more into profit for the company that can either be reinvested back in the company or returned to shareholders.  Their cash-to-debt ratio for the same years were both 0.17.  I prefer for company's I'm investing in to have very little debt on their books and to have a cash-to-debt ratio greater than 1.  This is the only real blemish from a fundamentals perspective.

Share Buyback:

Medtronic's shares outstanding decreased more years than not since the end of FY 2001.  They're bought back over 14% of the shares outstanding in that time, with an average of 1.39% purchased each year.  By repurchasing shares, Medtronic is able to increase EPS and management can return cash to shareholders this way by increasing the ownership share of the company for all the oustanding shares.

A negative number for the % change value means shares were bought back by the company and a positive value means the shares outstanding increased.

Dividend Analysis:

Medtronic is a dividend champion with 35 consecutive years of dividend increases.  Their current annual dividend sits at $1.04 for a current yield of 2.44%. MDT's annual increase for the last 1, 3, 5 and 10 years have been 7.78%, 8.95%, 17.13% and 15.48%. These numbers are different from the actual quarterly increases since these are based off the dividends paid out during each fiscal year.  Despite the really nice DGR, their payout ratio has only increased from 23.53% in FY 2001 to 30.12% in FY 2012.  The highest payout based off earnings was the recent FY 2009 rate of 38.86%.  Considering they've been growing the dividend with over 15% annual increases over the last 10 years, it's very nice to see that the payout ratio hasn't increased at the same rate.

Their FCF per share has been pretty good over the years.  Since FY 2001 they had only 2 negative years, both of them in very trying economic times in 2002 and 2009.  Their FCF payout ratio at the end of FY 2012 was a miniscule 36.2%.  With such a large cushion it leaves room for management to continue increasing the dividend without hurting the company's cash flow.

Return on Equity and Return on Capital Invested:

Medtronic's ROE has averaged 24.75% since 2001 with a low of 21.0% and a high of 32.1%.  Their ROCI has averaged 19.0% since 2001 with a low of 14.7% and a high of 25.1%.  For both ROE and ROCI I don't necessarily look for any absolute values rather I like to see stable or increasing levels over the long term.  Medtronic has done a good job on both of these fronts.  I would like to see both numbers increase when they close out FY 2013 in April.

Revenue and Net Income:

Since the basis of dividend growth is revenue and net income growth, we'll now look at how Medtronic has done on that front.  Their revenue growth since 2001 has been a great 10.22% per year and their net income has been growing at an 11.94% rate since 2001.  Since their net income has been growing faster than revenue their net income margin has increased from 18.84% to 22.35% between FY 2001 and FY 2012.  This means that management has been able to get operations more efficient and they are able to keep more pennies from every dollar of sales to reinvest in the company or return to shareholders.  Revenue has grown every year except since FY 2001.

Tangible Book Value:

Medtronic's tangible book value per share was a little bumpy in the first part of the period but has been growing very consistently since 2008.  Since 2001 they've averaged a 1.96% increase in tangible book value per share.  A company's tangible book value per share is what common shareholders can expect to receive if the firm went bankrupt and all of its assets are liquidated at their book values.  It takes out the intangible assets from the equity of the company.


The chart shows the historical high and low prices since 2001 and the forecast based on the average PE ratios and the expected EPS values. I have also included a forecast based off a PE ratio that is only 75% of the average low PE ratio for the previous 5 years and 10 years whichever is least.  Since I think the 5 year average low PE of 13.80 is going to be more typical for MDT, I'll use that number.  I like to the look to buy at the 75% Low PE price or lower to provide for additional margin of safety. In this case the target low PE is 13.80 and the 0.75 * PE is 10.35 . This corresponds to a entry price of $37.77 based off the expected earnings for FY 2013 of $3.65.  Currently Medtronic is trading at a $4.83 premium to the 75% low PE target price.


The average of all the valuation models gives a fair value $40.01 which means that Medtronic is currently trading at a 6.5% premium to the average fair value. I've also calculated the fair value with the highest and lowest valuation methods thrown out.   In this case, the DCF and DDM valuations are thrown out and the new average is $39.98.  Medtronic is trading at a 6.6% premium to this price as well.

Overall I would say that Medtronic is in the fair value range but a further pullback would be welcomed.  My average fair value calculation is more of a low value price target since I'm taking the low PE, dividend and PS ratios to calculate the value.  Picking up shares for less than my "average fair value" calculation price targets is usually a sign that you're getting a really good value on the shares as long as nothing has fundamentally changed with the company to give prices that low.  As as DG investor the starting yield is lacking on Medtronic but could be made up very quickly if their DG can remain at the elevated rate for several more years.

I thought we should also take a look at the potential returns that you could be looking at if you buy in at the $42.60 level.  If Medtronic can grow their EPS at the rates that I used in my DCF analysis then after 10 years their EPS will be $5.43.  Applying the 5 year average low PE ratio of 13.80 to the EPS would mean that shares would be trading for $74.89.  This would be a 75.79% return over 10 years.  However we also have to account for the dividends.  In that same time you would have received $14.57 in dividends if they can grow dividends at the rates I used in my DDM analysis.  This would represent a further return of 34.21% if dividends are not reinvested.  The 10 year total return would be 110%, for average annual return of 7.70%.  I can live with a 10 year return over 7% before inflation and approximately 4% after inflation.  I borrowed this idea from Dividend Growth Stock Investing.

Yesterday I went ahead and started a position with Medtronic.  I now have more of a pure play on the healthcare industry which was lacking in my portfolio.  I didn't get the best possible value but I will be looking to average down my position if a pullback in MDT shares occurs.  If the current yield rises to a 3.00% level I'll be picking up at least one more lot of shares.  The 2.75% yield level corresponds to a $37.82 price target and the 3.00% yield level is at $34.67.  Since the ex-div date is on 12/13 I'll be receiving their next dividend payment later this month.  Medtronic has moved their first quarter dividend up by a month to get the payout in before the potential tax increases.  I'm not too worried about the dividend tax increases, but I'll take the payment earlier to start the compounding process.

What do you think about Medtronic as a DG investment at today's prices?


  1. Pursuit,

    Another fine analysis. Your quantitative look at companies leaves no stone unturned.

    I would agree with your overall valuation and investment thesis. I think fair value for MDT probably ranges from about $39-43 per share. I would be okay buying shares at current market prices, but this is at the higher range of where I'd feel comfortable. BDX is similar for me. I think the fair value for BDX is probably between $75-80 per again it's a bit on the high side. Both high quality companies, however.

    Really not a lot to dislike about MDT. It's a great company that is anxious to return value to shareholders. It's a responsible steward of cash and produces products that will continue to be in demand, and increase in demand as our population ages.

    Best wishes!

    1. DM,

      Mdt is on the high end of the fair value range but i was willing to overpay just a bit for it. Ill be happy with the 7% return if they can grow eps and dividends the rates i calculated. So im happy with the purchase. Hopefully the markets will give me a chance to average down soon.

      Thanks for stopping by!

  2. Thanks for your detailed analysis.

    I like MDT right here and I just purchased shares recently as well. I'd love to average down on MDT, BDX and JNJ in the healthcare space if we ever get a correction. I may have to look into selling another put until I get the price I want.

    Take care.

    1. AAI,

      No problem. I would love to get a chance to average down in MDT and initiate a position in both BDX and JNJ. The latter 2 need at pretty big pullback before I'd start buying but that opportunity just might be coming. I need to check in more about getting the margin account so I don't have to tie up as much cash when I sell puts. I'll have to try and find out what happens in the possible scenarios. I know that it's pretty much just a credit account but I haven't looked into it that much.

      Thanks for stopping by!

  3. Medtronic seems like a excellent company. Stocks involved in healthcare have been out of favor for a long time. The sector of the economy thats been growing through thick and thin is healthcare. The prospects for companies like medtronic are still very bright.
