What happened

Shares of Arconic (NYSE:ARNC) jumped nearly 14% today after The Wall Street Journal reported that the high-performance metals and materials manufacturer has drawn buyout interest from capital management firms, including Apollo Global Management. Today is the first trading day since the report was issued late Friday evening.

Separately, Arconic today announced three updates for investors to take into account. First, it announced a large multiyear deal with Boeing to supply aluminum sheet and plate for all models of aircraft in the company's portfolio, including the 787, 777X, and fast-growing 737. Second, the materials specialist announced a collaboration with Lockheed Martin to develop 3-D metal printing techniques and products for aerospace applications.

Third, Arconic said it has created a new titanium alloy for high-temperature aerospace applications. The new material is 50% lighter than traditional nickel-alloy materials used in similar applications, better withstands oxidative stresses, and has been tested with U.S. military and commercial partners.   

As of 11:41 a.m. EDT, the stock had settled to a 10.6% gain.

So what

You could say Arconic is having a pretty good day. But it hardly erases the scars of the stock chart from the last year, including a 30% year-to-date slide (even after factoring in today's pop). The company has found itself embroiled in controversies, worries over its significant level of debt, concerns over the slow pace of growth, and a ho-hum full-year 2018 guidance. While there's a promising portfolio of products and technical capabilities, a turnaround of the business would not be easy for a company of its size (the market cap swelled past $14 billion in early January).

Of course, the erosion of value has made the potential for a buyout all the more attractive, albeit no less risky. That's because any acquisition will require the assumption of $6.4 billion in debt in addition to any potential premium paid on shares, with the current stock price valuing the company just shy of $10 billion. Therefore, it's likely no coincidence that Arconic poured it on fast and heavy today with operational updates. What's more, all three updates are tied to the highest-margin industry the company supplies: aerospace. 

Now what

In late April, Arconic's market cap collapsed below $10 billion for the first time since shortly after it emerged from its breakup with Alcoa. That came on the heels of some rather blunt admissions from the company's new CEO Chip Blankenship about the difficult but necessary road ahead.

The latest announcements provide some hope that the selling may have been overdone, but the turnaround is far from over or secure. More important, a sale to a capital management firm is not a slam dunk. Therefore, investors should continue to tread carefully with this high-performance-materials stock.
