Rolls-Royce (RR.) share price rises as £200m buyback plan, US Army MV‑75 engine tests and UK SMR momentum dominate today’s headlines (17 Dec 2025)

Rolls‑Royce Holdings plc (RR.) is back in focus on 17 December 2025 as shares climb in London, investors digest a new £200m interim buyback, and defence + nuclear catalysts build.

What’s happening with Rolls‑Royce (RR.) today

Rolls‑Royce shares were higher in London on Wednesday, with the stock trading around 1,123p (about £11.23) on a ~2.3% gain versus the prior close, according to 15‑minute delayed exchange data. ^[1]

Today’s focus is being shaped by three parallel storylines investors care about:

Capital returns: a newly announced £200 million interim share buyback that starts 2 January 2026. ^[2]
Defence momentum: Rolls‑Royce has begun AE 1107F engine testing tied to the U.S. Army’s MV‑75 FLRAA programme. ^[3]
Energy transition optionality: ongoing UK and industry interest around small modular reactors (SMRs), including new “pipeline” development activity reported today that recaps the UK’s first SMR site at Wylfa. ^[4]

Rolls‑Royce share price: today’s move in context

As of the latest London quote (delayed), RR. was indicated at 1,123p, up 25p (+2.28%) on the session, after opening around 1,108p and trading between roughly 1,102p and 1,124p. ^[5]

A few context points that matter for readers (and for search):

Rolls‑Royce’s market cap was shown around £93bn, with roughly 8.30bn shares in issue. ^[6]
The 52‑week trading range displayed on the London Stock Exchange page puts the high near 1,195p (late September 2025) and the low near 557p (mid‑January 2025). ^[7]
There were no new regulatory RNS items posted today on the exchange feed; the most recent listed update remains the buyback announcement from 16 December 2025. ^[8]

That “no new RNS” point matters because it tells investors the price action is being driven by news digestion and sector sentiment rather than a fresh filing this morning.

1) £200m interim share buyback: what Rolls‑Royce announced and why it matters

The biggest capital markets catalyst being discussed today is Rolls‑Royce’s decision to launch a £200 million interim share buyback programme after finishing its £1 billion buyback in November 2025. ^[9]

Key details (for investors and Google Discover readers)

Start / end: runs from 2 January 2026 and is expected to complete no later than 24 February 2026. ^[10]
Execution: Rolls‑Royce entered a non‑discretionary arrangement with UBS AG London Branch to execute purchases (UBS makes trading decisions independently within agreed parameters). ^[11]
Mechanics: shares bought under the programme will be cancelled, reducing share capital. ^[12]
Next major date: Rolls‑Royce expects to communicate FY2025 full‑year results on 26 February 2026, and says the broader 2026 buyback quantum remains subject to board review, with expectations to update alongside those results. ^[13]

UK market coverage continued to circulate the buyback headlines into today’s session, with live pricing widgets showing RR. higher during the morning. ^[14]

Why the market cares

Buybacks matter for three reasons:

They’re a signal of management confidence in cash generation and balance sheet flexibility.
They can mechanically improve per‑share metrics over time (all else equal) by reducing the share count.
They tend to attract “quality compounder” investor attention when paired with credible operating momentum.

Rolls‑Royce’s own buyback announcement reiterates recent scale: it cites 2024 underlying revenue of £17.8bn and underlying operating profit of £2.46bn. ^[15]

2) Defence catalyst: AE 1107F engine testing for the U.S. Army MV‑75 FLRAA

The second major narrative (and one that broadens Rolls‑Royce’s “civil aviation recovery” story into a defence technology story) is propulsion progress for Future Long Range Assault Aircraft (FLRAA).

Rolls‑Royce confirmed it has begun AE 1107 engine testing to support prototype delivery for the U.S. Army’s MV‑75 programme. ^[16]

What the company said

Each MV‑75 is set to use two AE 1107F engines, and Rolls‑Royce describes the configuration as focused on power density, cyber‑compliant controls, and survivability features. ^[17]
Testing is underway at the company’s Indianapolis campus, which Rolls‑Royce calls its largest U.S. facility. ^[18]
Rolls‑Royce said it has invested more than $1 billion over the past decade in upgrades and test capabilities supporting U.S. Department of Defense programmes. ^[19]

The company also frames AE 1107F as part of a broader engine family with substantial operational history, citing 90 million flight hours across 16 commercial and military platforms, and highlighting lineage connected to platforms including the V‑22 Osprey. ^[20]

A defence outlet briefing dated today also recirculated these details for broader readership, referencing the same testing milestone. ^[21]

Why this matters for RR. shareholders

For investors, FLRAA‑linked milestones are watched because they imply:

Potentially durable, multi‑year defence production and services work,
Greater exposure to government spending cycles (which can behave differently than airline demand),
Incremental support for the market’s re‑rating narrative: Rolls‑Royce as not just a turnaround story, but a portfolio of long‑cycle, high‑barrier engineering franchises.

3) Nuclear & SMR optionality: today’s “pipeline” news and the Wylfa anchor project

The third storyline isn’t a new UK government decision today—but it is part of the media cycle on 17 December because a fresh industry report focused on site development is adding momentum to the broader SMR narrative.

Today’s SMR-related industry development

A story published today reported that Fugro is partnering with UK startup Fermi Development to develop a portfolio of UK sites suitable for advanced reactors / SMRs, with Fugro contributing geoscience/site characterization and Fermi focusing on land, permissions, licensing and grid connection work. ^[22]

Within that coverage, the piece explicitly recaps the UK’s first SMR deployment plan at Wylfa, which is intended to use Rolls‑Royce SMR technology. ^[23]

The Wylfa SMR project: the verified facts readers should know

From UK government communication on the Wylfa decision:

Wylfa (Anglesey / Ynys Môn, North Wales) was selected as the site for the UK’s first SMR deployment. ^[24]
The initial project is planned for 3 SMR units, with a stated potential to host up to 8 in the longer term (subject to future decisions). ^[25]
Great British Energy–Nuclear (GBE‑N) is expected to start activity at the site in 2026, and the ambition is for SMRs to supply power from the mid‑2030s. ^[26]

From Rolls‑Royce SMR’s own November statement, the company describes Wylfa as the first UK site for its SMRs and positions it as the start of a long‑term fleet deployment approach. ^[27]

Why SMRs matter for the equity story—even now

SMRs are not a near‑term earnings driver in the way civil aerospace services are. But they matter because:

They shape investor expectations for optional growth platforms,
They can influence how the market values Rolls‑Royce’s engineering IP and long‑duration project pipeline,
They connect to broader themes: grid constraints, industrial electrification, AI/data‑centre power demand, and energy security.

4) AUKUS skills alliance: a smaller headline today with longer-term relevance

A separate item published today highlights how Rolls‑Royce continues to sit inside the broader UK‑Australia defence innovation ecosystem.

Cranfield University announced an Advanced Skills Alliance linking UK and Australian universities to accelerate skills and research needed for security/defence, supporting the AUKUS innovation programme. The press release notes “unprecedented industry involvement,” with input including Rolls‑Royce (alongside other major defence groups). ^[28]

This is not a “contract win” headline—but it reinforces the reality that AUKUS‑linked capability building is increasingly being treated as a workforce + R&D pipeline challenge, not only an industrial one.

What to watch next for Rolls‑Royce investors

If you’re writing for Google News/Discover, the “what happens next” section is where readers tend to stick—especially retail investors following RR.’s multi‑year rally.

Key dates and catalysts:

2 January 2026: interim buyback programme begins (subject to market conditions and programme parameters). ^[35]
24 February 2026 (no later than): expected completion date of the interim buyback. ^[36]
26 February 2026: expected timing for FY2025 results, and the likely moment for any update on the total planned 2026 buyback quantum. ^[37]
2026 onward: continued FLRAA prototype progress and follow‑on defence programme milestones; plus UK SMR workstreams as site activity ramps. ^[38]

Bottom line

On 17 December 2025, Rolls‑Royce (RR.) is trading higher and back in the spotlight because investors are weighing a near‑term capital return mechanism (buybacks) against two longer‑cycle strategic arcs: defence propulsion programmes and nuclear SMR optionality.

That combination—cash returns + durable defence exposure + energy transition positioning—helps explain why RR. remains one of the most closely watched industrial names on the London market going into 2026. ^[39]
