Rocket Lab's Germanium-Free Solar Cell Meets a Market Still Skeptical About Neutron
Published on 09/10/2026 at 15:02 | Editorial boerse-global.de
Rocket Lab is discovering that a technological breakthrough and a heavyweight institutional buyer are not always enough to offset a bruised tape. The stock closed Wednesday at EUR 54.30 after shedding 4.2% on the day, then clawed back some ground in pre-market trading Thursday, lifted by a product launch and fresh purchases from a prominent investor.
A Solar Cell That Sidesteps a Supply Chain Risk
The catalyst arrived Tuesday, when Rocket Lab moved its IMM Apex solar cell into production. The component delivers an initial efficiency of 31.5% while weighing 40% less than conventional cells, and — critically — it contains no germanium whatsoever. That matters because China briefly restricted germanium exports; while the curb is suspended through the end of November, the US space industry's reliance on the material remains a live vulnerability.
Rocket Lab pitches the cell as a drop-in replacement for germanium-based products, which typically run between 28% and 32% efficiency. The underlying IMM architecture is hardly a gamble for the company: it already flew on NASA's Ingenuity Mars helicopter and carries more than a decade of orbital heritage.
ARK Keeps Adding to Its Stake
Alongside the product news, ARK Invest continued to build its position. The ARKX fund picked up roughly 2,341 additional Rocket Lab shares, following earlier purchases of about 705,000 shares across three ETFs within two days, worth some USD 44.4 million. Such accumulation points to institutional conviction, even if it has not been enough to fully absorb near-term selling pressure.
The August Print That Started the Slide
Much of Wednesday's decline was self-inflicted. Rocket Lab reported results in early August that missed consensus: a loss of USD 0.08 per share against expectations of USD 0.06, while revenue of USD 234.07 million edged past the USD 231.62 million forecast. The backlog nonetheless hit a record USD 2.36 billion.
Should investors sell immediately? Or is it worth buying Rocket Lab?
A sector-wide downdraft compounded the damage midweek, triggered by the expiration of a lock-up on insider sales at SpaceX. AST SpaceMobile, Intuitive Machines and Planet Labs all retreated in sympathy, and SpaceX paper slid as well.
Where the Charts Stand
The shares now trade roughly 15% below their 50-day moving average of EUR 63.56 and about 59% under the 52-week high of EUR 133.80. An RSI of 35.8 points to oversold conditions — a setup that may help explain ARK's willingness to buy. Even after the pullback, the stock sits around 67% above its 52-week low of EUR 32.60. The gap to the 200-day average, some 24% below, underscores the medium-term downtrend.
Washington's Long Game
On Wednesday, the Trump administration, through Transportation Secretary Sean Duffy, unveiled a new SPACE Task Force aimed at enabling 10,000 FAA-licensed launches and reentries annually by 2035 — up from 217 US launches in 2025. The ambition would lift the entire sector into a new growth dimension, though investors treated the long-horizon target with skepticism, opting for profit-taking instead.
Adding to the bullish case, SpaceX reportedly stopped accepting dedicated Falcon 9 bookings beyond 2028 as it pivots to Starship. That opens a window for rivals including Rocket Lab, Stoke Space and The Exploration Company.
Neutron Remains the Swing Factor
At the heart of the debate sits Neutron, Rocket Lab's answer to the medium-lift class and its bid to carve share from the SpaceX–Blue Origin duopoly. A Seeking Alpha analysis published Thursday made the point bluntly: a brimming backlog does not retire what it calls "Neutron risk." CEO Peter Beck positions Rocket Lab as the third-largest payload launch provider today, pointing to an industry set to expand from roughly USD 360 billion to a projected USD 1.7 trillion within five years. Whether Rocket Lab captures a disproportionate slice of that growth hinges on Neutron arriving on schedule and performing reliably — not on how many contracts are already signed.
Berenberg reaffirmed its buy rating on Thursday with a USD 83 price target. Beck's own emphasis on Mars probes built in a fraction of the time earlier NASA projects required speaks to operational muscle beyond the launch business itself.

Well-Funded Challengers Circle
The risk side deserves equal weight. Stoke Space closed a Series E round exceeding USD 1 billion, bringing total funding to USD 2.3 billion — capital earmarked for a fully reusable rocket whose first stage is slated to fly in 2027. The Exploration Company raised USD 450 million in parallel. Competition in the medium- and heavy-lift segments is intensifying precisely where Neutron intends to compete. Until Neutron reaches routine operational service, every growth projection for Rocket Lab remains tethered to an unproven assumption.
What Analysts See
Sentiment among the sell side stays broadly constructive despite the volatility: 13 buy ratings, 5 holds and a single sell produce an average price target of USD 108.83, implying meaningful upside from recent US trading levels. Beck framed the strategy succinctly in an interview — Rocket Lab will never outprice rivals like Amazon and SpaceX, so it must outsmart them technologically.
For investors, the picture is genuinely two-sided. Near-term pressure from missed expectations and sector weakness collides with long-term analyst optimism and institutional buying. The next real test is not another contract announcement but tangible progress on Neutron — any credible word on a first-flight date is likely to move the stock more than a fresh order ever would.
