Why I'm Buying Shares of IPG Photonics Corporation

The future of manufacturing is here, and I plan on owning one of the companies poised to benefit the most.

Fiber optic lasers are the wave of the future, with their ability to cut and weld huge pieces of metal while using up less energy and being more reliable than the standard carbon dioxide-based lasers that have been used for decades.

Though there are several companies that offer fiber lasers, IPG Photonics (NASDAQ: IPGP  ) was the first-mover in the industry, and it remains the only player that is both vertically integrated, and solely focused on the technology.

How IPG fits into my portfolio
For over three years, I've been calling out one company every month that I'm putting my Roth IRA money behind. Over that time, this portfolio has returned 36%, far outpacing the S&P 500, which has returned 24% over the same time frame.

Currently, IPGP makes up 8% of my IRA -- which is a lot -- but I think the opportunity here is too good to pass up. The company offers exposure to the manufacturing sector, has broad geographic diversity, and is fairly priced. Read below to get more details.

Going after material processing OEMs
Usually, it's a good thing to diversify one's business as much as possible. But with IPG, the focus has become narrower and narrower -- and it's not necessarily a bad thing. Original equipment manufacturers, or OEMs,  have long used carbon dioxide  lasers or other precision cutting devices in order to cut or weld large pieces of metal.

Fiber lasers, which IPG specializes in, are far stronger, efficient, and cost effective than traditional cutters/welders. This has presented a unique opportunity for IPG: OEMs represent lucrative, repeat business that is up for grabs.

In 2009, IPG got 76% of its revenue from material processing companies; by 2013, that number was all the way up to 94%. Currently, it offers a full suite of lasers that OEMs can use, and all but one showed fantastic strength over the last quarter.

Beating the competition
IPG is certainly not the only player in the fiber laser industry. Coherent (NASDAQ: COHR  ) and Rofin-Sinar (NASDAQ: RSTI  ) both offer fiber lasers as well. But those are just one of five different types of lasers that these companies offer, and neither is vertically integrated.

That provides some safety for investors -- as it's easier to control costs during downturns when a company isn't vertically integrated, and a greater variety of lasers provides more diversification.

But with fiber optic lasers, I believe the long-term trend is undeniable. There's a great risk/reward ratio from going all-in on this technology. Though there will certainly be stops and starts on the path toward adoption, it's difficult for me to see a future where fiber lasers aren't adopted by the vast majority of OEMs.

IPG's single focus on the industry gives me confidence that it will win the battle for business. It spends all of its research and development as well as capital expenditures solely on fiber lasers. And the company's vertical integration -- which admittedly is a drag during slow economic times -- allows it to offer products for far cheaper than the competition.

IPG's leadership believes much the same, as it announced it will be making major capital investments to expand the company's ability to meet demand from OEMs. The company's book-to-bill ratio currently sits above one, which means that currently, customers can't get enough of the company's lasers.

With shares currently trading for about 21 times earnings, and a huge opportunity in front of it, I think now's the time to buy shares of IPG. When Fool trading rules allow, I'll be adding shares to my Roth IRA.

IPG already has a hand in this, and you can't afford to miss it
"Made in China" -- an all too familiar phrase. But not for much longer: There's a radical new technology out there, one that's already being employed by the U.S. Air Force, BMW and even Nike. Respected publications like The Economist have compared this disruptive invention to the steam engine and the printing press; Business Insider calls it "the next trillion dollar industry." Watch The Motley Fool's shocking video presentation to learn about the next great wave of technological innovation, one that will bring an end to "Made In China" for good. Click here!

    I should have said CO2 lasers--instead of carbon lasers--were the industry standard. Sorry for the confusion.

    The last time I checked, Rofin-Sinar is vertically integrated. They own Nufern (fibers), Dilas (diodes), Corelase (laser engines), and Optoskand (connectors and switches).

    The big fear in the industry are the Chinese. They are taking over the lower power pulsed lasers (impossibly low prices) and the low power continuous wave fiber lasers. JDSU has also been moving into the high power business.

    Obviously, competition is increasing and the entire laser and optics industry is maturing as indicated by consolidations and slower annual growth rates. IPG has been trying to find "new applications" as evidenced by their mid-IR laser offering. New applications take years to get accepted into industry. IPG's main application has been to replace gas and bulk lasers: an old application with new technology.

    Even IPG has said that the biggest threat to fiber lasers are direct diode lasers. Teradiode just announced a 4kW fiber coupled diode laser.

    Let's talk in a few years to see if your investment works out. As a general rule, I wouldn't purchase stocks in a mature optics or laser company.

    Several people have mentioned the barriers to entry for new technology in the laser market. Some interesting quotes are almost contradictory in their assessments, for example one writer says "New applications take years to get accepted into industry" in the same paragraph he writes "he biggest threat to fiber lasers are direct diode lasers". Without concern for the fact that fiber lasers are all diode pumped, the author claims "new is better" and in the same breath claims "new is bad". It just makes no sense.

    It's taken quite a few years for IPG to prove its technology and they've now begun to replace CO2 gas lasers in the cutting and welding applications. There's always room for improvement and no doubt in 5 or 20 years the next wave of innovation will be tested and broadly accepted by the industry.

    Zeekerdude, that is some good commentary -- not sure either way as I definitely don't know this industry but I appreciate you taking the time to comment. You should "back it up" using CAPS; go to, and start your scorecard, perhaps with a thumbs-down on one or more of these companies. Then, in addition to just scoring Brian, you can score yourself too, and share your expertise with our community.

    Fool on,
