Mercury Systems Inc (MRCY)

Q3 2026
▲3▼1

Mercury Systems surged on record orders, but profit miss stung

  • Record bookings and backlog Mercury booked a record $348M in Q1 and $660M in Q4, up 93%, pushing backlog above $1.9B. That means customers ordered far more than the company shipped, a sign of strong future sales.

    Record orders and backlog were the main engine behind the stock's rise.

  • Revenue beats and Palantir partnership Revenue beat expectations in both quarters (Q1: $235.8M, +14.2%; Q4: ~$290M, +9%). A new partnership with Palantir aims to automate Mercury's factories and supply chains for U.S. military programs, which could improve efficiency and margins.

    Revenue growth and the Palantir deal were key positive catalysts during the period.

  • Analyst upgrades and strong stock performance Analysts upgraded the stock, which rose 47% after Q1 results and 44% year-to-date. Management guided FY27 revenue near $1.1B, giving investors confidence in continued growth.

    Upgrades and the stock's sharp rise reflect improving sentiment and forward guidance.

  • Profit miss and margin pressure Q4 adjusted EPS of $0.37 missed estimates and fell 21% year-over-year, while gross margin slipped to 30.6%. Shares dropped over 9% as investors worried that growing sales weren't translating into profits.

    The earnings miss and margin decline were the main negative force, causing a sharp sell-off.

Record Q4 bookings and backlog, but profit miss and margin pressure

  • Record Q4 bookings and backlog Mercury reported record fourth-quarter bookings of $660 million, up 93% from a year ago, and a record backlog above $1.9 billion, up 38%. That means customers are ordering far more than Mercury is shipping, which points to strong future revenue and supports the stock.

    This is the core new fundamental driver of demand and future revenue.

  • Q4 revenue beat and strong FY27 guidance Quarterly revenue of about $290 million beat analyst estimates by over 9%, and Mercury guided fiscal 2027 revenue to approach $1.1 billion with adjusted EBITDA near $200 million. That suggests the order boom is starting to turn into actual sales and profit.

    It shows the demand is converting into revenue and gives a forward profit target.

  • Adjusted earnings miss and margin pressure Despite the revenue beat, adjusted earnings of 37 cents per share missed estimates and fell 21% from a year earlier, while gross margin slipped to 30.6%. The stock fell more than 9% on the day, showing investors are worried about profitability even as sales grow.

    It is the main counterweight explaining why the stock dropped despite strong bookings.

  • Palantir alliance to automate factories Mercury and Palantir announced a strategic alliance to automate material planning and factory operations for U.S. military programs, using Palantir software to remove manual bottlenecks and build a digital twin of the business. Over time this could raise output and improve margins.

    It is a new technology and efficiency catalyst that could lift future profits.

Rolls-Royce Holdings PLC (RR.LSE)

Q3 2026

Rolls-Royce profit jumps, guidance raised on defense and power demand

  • H1 profit surge and raised guidance Rolls-Royce's first-half operating profit jumped 46% to £2.5bn, prompting the company to raise its full-year profit guidance to £4.7–4.9bn. This strong financial performance was the main driver of the stock's rise.

    The profit beat and guidance raise are the central new financial events that directly lifted the shares.

  • Defense and power systems growth A £15bn boost to the UK defense budget supports Rolls-Royce's £17.4bn order backlog. Meanwhile, its power systems unit benefits from a looming 100GW US power shortfall and booming data-center demand, with orders up over half and another hyperscaler deal near.

    These are new, concrete demand drivers that underpin future revenue and were highlighted as key positives this period.

  • New nuclear deals Rolls-Royce signed new nuclear agreements in Sweden, the UK, and Japan, adding long-term revenue potential. These deals strengthen its position in the small modular reactor market and support future growth.

    The nuclear deals are a fresh positive development that expands the company's long-term opportunity pipeline.

  • SMR sourcing and weak China luxury demand Risks remain: SMR reactor vessels must be sourced overseas, angering UK politicians and unions and potentially delaying approvals. Chinese luxury car demand is still weak, and quantum computing work is only an early-stage positive signal.

    These are the main counterweights that could cap gains or delay projects, providing a balanced view.

Rolls-Royce wins new nuclear deals but faces UK content scrutiny

  • Sweden SMR contract and UK/Japan nuclear tech deals Rolls-Royce won a contract to build three small modular reactors in Sweden and signed nuclear technology agreements with the UK and Japan. These deals turn policy support into real revenue commitments, strengthening the long-term growth story and supporting the share price.

    This is a new, concrete win that adds to Rolls-Royce's nuclear order book and future revenue.

  • Overseas sourcing for SMR reactor vessels raises political risk Rolls-Royce is buying key reactor parts from South Korea or the Czech Republic because no UK supplier can make them. This has upset UK politicians and unions, and could slow approvals or force costly changes, weighing on the SMR programme and the shares.

    It is a new negative development that could delay or complicate a key growth project.

  • Quantum computing partnership for turbine design Rolls-Royce is working with Quantinuum and others to explore quantum computing for designing better gas turbines. If successful, this could cut development costs and improve engine performance over time, a small but positive long-term signal for the shares.

    It is a new technology collaboration that could enhance future competitiveness.

  • China consumer weakness hits luxury car sales Rolls-Royce car sales in China have fallen as consumers there spend less on luxury goods. While the decline is less severe than for mass-market brands, it still points to weaker demand in a key market, a mild drag on sentiment for the company.

    It is a new data point showing demand pressure in an important region.

Rolls-Royce Soars on Record Profit Upgrade and Booming Defense & AI Demand

  • UK defense budget boost lifts demand outlook The UK unveiled a £15 billion defense spending increase, raising the budget to 2.7% of GDP by 2029. This directly benefits Rolls-Royce's defense arm, which already has a £17.4 billion order backlog, by increasing future orders for military engines and services.

    This is a major new demand driver for Rolls-Royce's defense business, directly boosting future revenue and profit potential.

  • US power shortfall opens new market for gas engines Bank of America warns of a 100-gigawatt US electricity shortfall by 2030, with data centers driving demand. Natural gas turbines are sold out, pushing developers to Rolls-Royce's gas reciprocating engines, creating a new growth avenue beyond aerospace.

    This highlights a new, large addressable market for Rolls-Royce's power systems segment, driven by AI data center growth.

  • H1 profit jumps 46%, guidance raised sharply Rolls-Royce reported a 46% rise in first-half operating profit to £2.5 billion and raised full-year guidance to £4.7-4.9 billion, up from £4-4.2 billion. Strong performance across civil aerospace, defense, and power systems drove the beat, with free cash flow also rising.

    This is the core earnings event that directly validates the company's turnaround and boosts investor confidence.

  • Data center orders surge, hyperscaler deal imminent Rolls-Royce's power systems unit grew organic revenue 28% and profit 72%, with the data center order book expanding by over half in H1. The CEO said another major hyperscaler deal is near, and orders are already being taken for 2028, signaling strong future growth.

    This shows concrete momentum in the fast-growing data center power business, a key new profit engine.
