Karman Holdings (KRMN) shares dropped 11% week-to-date following a critical short-seller report from J Capital. The firm raised concerns about weak internal controls, questionable acquisition practices that disclosed assets as immaterial despite high prices, and an inflated valuation with an EV/EBITDA ratio of 28—a 70% premium to S&P 500 stocks and 50% premium to aerospace and defense peers. This marks another setback for the recently IPO'd defense and space components maker.

Rocket Lab (RKLB) is diversifying beyond launch services by expanding its spacecraft component manufacturing capabilities through acquisitions including Sinclair Interplanetary, Planetary Systems, and SolAero Technologies. The company now offers reaction wheels, star trackers, batteries, solar solutions, and optical systems to commercial and government customers. With projected earnings growth of 81.48% in 2026 and 240% in 2027, RKLB trades at a premium valuation (32.02X forward P/S) compared to the industry average of 7.81X, and has gained 30% over the past year.

SpaceX's IPO on Nasdaq (ticker SPCX) has validated the commercial space sector at scale and triggered investor interest in public launch companies. Rocket Lab (RKLB) is positioned as the leading alternative, with record Q1 2026 revenue of $200.3M, a $2.2B+ backlog, and its Neutron medium-lift rocket expected to debut in 2026 as a potential Falcon 9 competitor. Other players like Firefly Aerospace and Karman Holdings offer distinct exposure to the broader space-systems landscape.

Two space and defense companies are converting strong backlogs into revenue growth amid rising global defense spending. Karman (KRMN) reported record Q1 2026 revenue of $151M (+51% YOY) with a $1B+ backlog, though its stock has fallen 40% YTD and trades at a high P/E of ~200. AeroVironment (AVAV) boasts a $1.1B funded backlog and $4.6B in YTD awards with 143% YOY revenue growth, despite missing analyst predictions and a 40% YTD decline. Both stocks are favored by Wall Street analysts despite recent selloffs.

SpaceX's anticipated $75 billion IPO at a $1.75 trillion valuation is reshaping the space sector and creating investment opportunities across publicly traded space companies. Starfighters Space announced a partnership with Mu-G Technologies to respond to a NASA RFI for commercial microgravity services, while other space sector companies are benefiting from increased government spending on defense, lunar initiatives, and commercial space infrastructure.

Karman, a defense company that went public in February 2025 at $22/share and peaked at $115 in January 2026, has dropped 40% but shows strengthening fundamentals. Q1 2026 results exceeded expectations with 51% YOY revenue growth to $151.2M and doubled adjusted EPS. The company raised full-year guidance, boasts a $1B backlog (61% YOY growth), and has 90% visibility into 2026 revenue. With new CEO Jon Rambeau's 30 years of defense industry experience and analyst price targets implying 65% upside, the stock appears better positioned for long-term success despite elevated valuation.

Karman Space & Defense (KRMN) stock fell 6.8% despite beating earnings expectations with $151.2M in sales (vs. $150.2M expected) and $0.11 EPS. The company reported 51% YoY sales growth, reversed prior losses to profitability, and raised 2026 guidance to $720-735M revenue. However, the stock remains expensive at 17x sales and 468x earnings.

A significant bottleneck in launch capacity is driving up prices across the space industry. SpaceX has raised Falcon 9 pricing, while competitors like Rocket Lab face delays. The shortage creates opportunities for launch providers and suppliers but pressures constellation operators. Key beneficiaries include Rocket Lab, Karman Holdings, and Firefly Aerospace, while AST SpaceMobile faces risks from Blue Origin's New Glenn failures.

Aerospace and defense stocks surged to record levels as Trump indicated a sustained military campaign against Iran is ahead, with the most intense phase still to come. Defense leadership confirmed the operation will extend beyond initial strikes, driving market expectations for increased demand for advanced weapons systems, air defense, and surveillance technologies.

U.S. defense stocks surged Wednesday following reports that the Trump administration is moving closer to potential military action against Iran. The SPDR S&P Aerospace & Defense ETF gained 2% while the Global X Defense Tech ETF rose 2.7%. Military buildup in the region includes two aircraft carriers, multiple warships, and hundreds of fighter jets. Prediction markets show rising odds of a U.S. strike on Iran, with 55% probability by March 15 and 67% by June 30.

Ten large-cap stocks experienced significant declines last week. Pinterest fell 21.73% after missing Q4 earnings and issuing weak Q1 guidance with multiple downgrades. DraftKings dropped 18.65% following disappointing Q4 results and below-estimate FY26 guidance. Other major losers included Astera Labs (down 23.74%), Medpace (down 20.69%), Zillow (down 20.89%), and Flutter Entertainment (down 18.88%), driven by earnings misses, analyst downgrades, and broader tech sector concerns about AI trade profitability.

January 2026 saw extreme stock movements driven by earnings surprises and sector disruptions. Top gainers included SanDisk (up 150%), Cameco (up 37%), and Lockheed Martin (up 30%), while software stocks suffered historic declines with Braze, HubSpot, Rubrik, Guidewire, and GoDaddy all posting worst months on record. Microsoft's weak Azure guidance triggered a broader software sector selloff, with the IGV ETF down 14% for the month.
