Amentum's profit beat and new contract wins offset revenue miss and NASA headwind

NASA COSMOS contract win Amentum won NASA's COSMOS contract to run mission operations and astronaut training for Artemis, the Space Station and more. This adds long-term work and supports future revenue, helping lift the stock.
New contract award directly boosts AMTM's demand outlook.
Q2 revenue miss but raised profit guidance Q2 revenue fell short and the stock dropped 15%, but the company raised its full-year profit and earnings guidance, with net income jumping. The market first focused on the miss, then on the improved profitability.
This is the main earnings event that moved the stock sharply both ways.
UK defence framework with Babcock Amentum joined a five-year Babcock framework to support UK defence programmes, including nuclear and submarine work. This secures steady, long-term engineering revenue and strengthens its international defence business.
New contract expands AMTM's addressable market and revenue visibility.
NASA workforce directive cuts 2027 revenue Amentum said NASA's workforce directive will cut about 3% from fiscal 2027 revenue, though the rest of the business should grow mid-single digits. This is a real headwind that partly offsets the new contract wins.
It is a new, specific negative factor that tempers the positive outlook.

TransUnion (TRU)

Q3 20268 Jul – 25 Sep 2026

TransUnion's strong quarter and raised guidance offset by regulatory threat

Q2 beat and raised 2026 guidance TransUnion reported second-quarter revenue of $1.31 billion, up 15%, and adjusted earnings of $1.23 per share, beating estimates. Management raised full-year revenue and earnings guidance, citing strength in U.S. Financial Services and Emerging Verticals. This directly boosts investor confidence and supports a higher stock price.
This is the core positive fundamental driver for the period, showing accelerating growth and higher future expectations.
OneTru migration and new products drive growth TransUnion completed major migrations of U.S. credit customers to its OneTru platform and accelerated new product launches globally. U.S. Markets revenue grew 11%, with international growth led by India, the U.K., and Canada. This operational progress supports revenue growth and efficiency, pushing the stock up.
It shows tangible execution on strategic priorities that underpin the raised guidance and future growth.
Regulatory threat from FHFA on credit scoring FHFA Director Bill Pulte directed Fannie Mae and Freddie Mac to allow all lenders to use VantageScore, ending FICO's monopoly, and criticized credit reporting agencies for overcharging. TransUnion shares fell over 7% as investors feared pricing pressure and reduced demand for its credit scoring services.
This is a new, material regulatory risk that directly threatens TransUnion's business model and stock price.
Geopolitical tensions and oil spike President Trump declared the Iran ceasefire over, sending oil prices up 7.5% and triggering a broad risk-off move. TransUnion fell 2.8% as rising bond yields and inflation fears reduced the value of future cash flows for growth-sensitive business services firms.
It explains a short-term negative price move due to external geopolitical factors, though less central than company-specific news.
