A Look at Constellium (NYSE:CSTM) Valuation Following Extended Aerospace Alliance With Embraer

Simply Wall St

Constellium (NYSE:CSTM) just made headlines with its announcement to extend a long-term partnership with Embraer, one of the heavyweights in global aviation. This deal will see Constellium continuing to supply high-performance aluminum solutions, including its advanced Airware alloy, across Embraer’s commercial, executive, and defense divisions. For investors, this agreement signals more than a continuity plan. It could be a sign that Constellium's products are increasingly indispensable to major players in the aerospace industry, potentially opening doors for higher shipment volumes and even stronger pricing power over the coming years.

Taking a step back, this announcement lands at a curious point in Constellium’s story. After surging about 45% year-to-date, the stock has managed a double-digit gain over the past three months but is still trading below its level from one year ago. The bigger picture shows momentum slowly rebuilding following a period of underperformance, with management touting recent gains in annual revenue and a striking improvement in net income growth. Combined with a growing focus on aerospace and a consistent drumbeat of innovation, this latest deal puts Constellium back in the conversation for growth-focused investors.

With shares catching a second wind and the Embraer extension on the books, investors may be considering whether Constellium is trading at a discount or if the market has already started pricing in its next phase of growth.

Most Popular Narrative: 18% Undervalued

The most widely followed narrative around Constellium suggests that shares are trading at a notable discount to what analysts view as fair value.

Ongoing operational improvements, particularly at the Muscle Shoals facility, along with robust cost controls under the Vision 25 program, are improving manufacturing efficiencies and reducing input costs. These developments could enhance gross and net margins over time. Positive effects from trade tariffs and regionalization trends are making Constellium's domestically produced products more competitive in the U.S. and protecting market share, potentially boosting contracted volumes and strengthening revenue stability.

Big growth is being projected, and it's not just about top-line gains. Want to know which bold financial levers analysts believe Constellium will pull to hit this fair value?
