Key Highlights

  • L3Harris Technologies (NYSE:LHX) closed at USD 243.84 on October 19, 2026, about 12% below its August 17 close of USD 278.38 (own arithmetic), and reports third quarter results before the open on October 29, 2026 with EPS expected near USD 3.06.
  • AST SpaceMobile (NASDAQ:ASTS) closed at USD 41.87, up 2.98% and about 5% above its low, after European carriers were reported on October 19, 2026 to be exploring a joint spectrum bid for about 500 million subscribers.
  • X-Energy (NASDAQ:XE) closed at USD 10.54, up 1.74%, after Amazon agreed on October 19, 2026 to fund 12 small modular reactors totalling 960 megawatts, and Morgan Stanley cut its target to USD 34 on October 14.
  • Defense stocks fell as the S&P 1500 aerospace and defense index lost nearly 19% from its early August high through October 15, 2026, on worries that the November midterm elections could curb the defense budget.

L3Harris Technologies (NYSE:LHX): Down 12% Since Its CEO Exit

No company announcement dated October 19, 2026 explains the 1.88% fall. The drivers are cumulative. The stock fell 8.6% on July 30, 2026, a move that erased about USD 4.8 billion of market value, after the second quarter report, and Kubasik's exit followed on August 17, 2026. Press reports on August 19, 2026 described earlier internal complaints, and a law firm opened an investigation on October 15, 2026. Concerns about slower defense budgets have also outweighed strength in missiles, leaving the shares down nearly 20% year to date as of early October. RBC cut its target to USD 265 from USD 310 on October 15, 2026, and the shares have not regained the USD 277.06 reached at the close of July 31, 2026. L3Harris Technologies (NYSE:LHX) has built a strategic investment structure around Missile Solutions through a new subsidiary, AXYV Inc., with preferred stock that converts into common shares if a qualified offering completes by December 31, 2027. Volatile markets pushed the target date to mid-2027. Demand remains strong: a USD 6 billion THAAD award was reported in early October 2026, backlog reached USD 42 billion, and a USD 876 million Navy Next Generation Jammer Low Band award came on October 19, 2026. Outside capital, if the offering proceeds, would help fund missile manufacturing development and construction without adding to the parent balance sheet. A minority sale also gives the unit a market value that sits visibly outside a large defense conglomerate. The consensus mean target is USD 326.06, well above the quote, but RBC at USD 265 shows how views have narrowed.

AST SpaceMobile (NASDAQ:ASTS): Up 2.98% Near Its Low

The catalyst was reported on October 19, 2026: Europe's largest carriers were said to be exploring a joint satellite spectrum bid, and a letter of intent was described as covering a possible 500 million subscribers. The shares rose as much as 6.86% to USD 43.45 intraday before closing up 2.98%. No financial terms were disclosed, so the letter of intent is a step toward a commercial agreement, not signed revenue. The rise followed weak trading in which the stock was still well below its key moving averages and near its 52-week low. The company also published a separate European update on October 19, 2026, describing collaboration with European mobile network operator partners, which gave the rally a company-sourced anchor beyond the carrier headlines. In its October 20, 2026 update AST SpaceMobile (NASDAQ:ASTS) said it has more than 60 gateways deployed, installed or planned and more than 60 mobile network operators covering over 3 billion subscribers. A convertible notes offering lifted pro forma liquidity above USD 3.7 billion, which funds satellite builds, but convertible notes can dilute holders if converted. Spectrum is the key input: the company combines partner operator spectrum with access to 45 MHz of mid-band mobile satellite spectrum in North America and priority rights to 60 MHz of S-band spectrum globally, and its satellites can tune across about 1,150 MHz, subject to regulatory approvals. Revenue guidance of USD 150 million to USD 200 million follows a second quarter revenue miss, so sales must climb through the second half. Launch timing for Block 2 BlueBird satellites, regulatory approvals and definitive agreements with carriers remain open items, and SpaceX is a direct rival.

X-Energy (NASDAQ:XE): Down 54% From Its IPO Price

The IPO priced at USD 23.00, USD 4 above the original USD 16 to USD 19 range, raised about USD 1.02 billion and opened at USD 30.11 on April 24, 2026. The shares have since lost nearly two thirds of their value from the offering price, and the October 14, 2026 Morgan Stanley target cut came with the stock already weak. The Amazon news was a company-specific positive, yet the shares gave back their premarket gain, which shows sellers are using strength. Ark Investment Management had indicated interest in up to USD 105 million of shares at the offering price, and Amazon was the largest holder, so institutional support at the IPO was strong. X-Energy (NASDAQ:XE) designs small modular reactors and advanced nuclear fuels. Small reactors aim to cut cost and schedule risk through factory production, though mass manufacturing may take about a decade to deliver benefits. Amazon held 24.3% after the IPO, and the company reported a 2025 net loss of USD 398.9 million on revenue of USD 109.1 million. Founded in 2009 and based in Rockville, Maryland, it is classed as a developmental-stage company, so reactor sales at scale are still ahead. The Amazon stake gives the company a strategic anchor customer and investor.

Where Things Stand

The three are long-duration bets whose demand is clear but whose cash flows lie years away, so higher rates and election risk weigh on valuations. L3Harris has a backlog near USD 42 billion and a USD 6 billion THAAD award, yet a chief executive exit on August 17, 2026 and a delayed Missile Solutions listing hang over it. AST SpaceMobile guides to revenue of USD 150 million to USD 200 million in 2026. X-Energy has a net loss. Nothing in this article is investment advice. Next filings from L3Harris Technologies (NYSE:LHX) will add detail. Fresh disclosure from AST SpaceMobile (NASDAQ:ASTS) is the next test. Official notices from X-Energy (NASDAQ:XE) remain the best guide.
