RWS grew 3 percent in FY2026, but its core localization business kept shrinking

What changed and when

27 October 2026. RWS issued its FY2026 year-end trading statement (unaudited, year ended 30 September 2026). Reported group revenue came in at about £700m, up roughly 2 percent, with organic constant currency (OCC) growth of about 3 percent, against a 0.7 percent OCC decline the prior year. Adjusted profit before tax (PBT) was in line with market expectations and about 9 percent above FY2025's £60.4m. Adjusted PBT margin rose to about 9.4 percent from 8.8 percent. Net debt, excluding leases, rose to about £38m at 30 September 2026 from £32.5m at 31 March 2026, after RWS paid the initial £16.5m cash consideration for its Obviously Group acquisition.

By segment, for the full year, RWS described Generate as delivering double-digit OCC growth, Transform as a mid-single-digit OCC decline, and Protect as mid-single-digit OCC growth. None of those three is given as an exact percentage in the trading statement, which is why the table below marks the precise full-year segment figures "not reported."

11 June 2026. RWS's half-year report, for the six months to 31 March 2026, gives the exact numbers the trading statement doesn't. Generate revenue rose from £68.7m to £99.4m, up 52.0 percent OCC, and became 28 percent of group revenue. Transform revenue fell from £226.4m to £210.1m, down 4.6 percent OCC (down 7.2 percent reported), while staying the largest segment at 58 percent of group revenue. Protect revenue rose from £49.2m to £50.7m, up 3.3 percent OCC, at 14 percent of group revenue. Group-wide, RWS said AI-related products and services reached 32 percent of revenue in H1 FY2026, up from 26 percent in H1 FY2025.

23 to 30 September 2026. Forrester published The Forrester Wave: Localization Services, Q3 2026, evaluating 11 vendors on 27 criteria. RWS announced on 24 September that it was named a Leader, claiming the top score on 18 of the 27 criteria. Welo Global, the holding company that now sits above the Welocalize brand (alongside Welo Data, Park IP, Welo Life Sciences, Opal and Adapt), announced on 30 September that it was also named a Leader, one of four in total, claiming the top score on 17 of the 27 criteria. Two localization vendors publicly claimed analyst-recognized leadership in the same week RWS's own numbers show the category shrinking for the company with the largest share of it.

3 August 2026, pending. RWS had separately agreed to acquire Acogroup, the parent of Acolad, a deal still working through approvals as of the October trading statement. The 27 October statement says French regulatory clearance and Works Council approvals have been received and completion is expected within two weeks. Acolad's own 2025 revenue has been reported elsewhere at roughly £182m, almost all of it translation and localization. That revenue, once consolidated, lands inside Transform, the segment that just posted another organic decline, not inside Generate.

The numbers, lined up

Why one segment shrinks while the other grows, inside the same company

RWS is not describing Transform's decline as an accident. The company's own language, repeated in both the April 2026 trading update and the June half-year report, is that Transform is being deliberately "pivoted" from a human-translation-volume business to a "technology-first" one. Read plainly: RWS is routing more of the words it used to bill human linguists to translate through machine translation and large language models first, with people reviewing rather than translating from scratch. That lowers cost per word, but it also lowers revenue per word faster than volume grows, which is the arithmetic behind a segment that is 58 percent of the company shrinking even while nobody at RWS is describing it as a crisis.

Generate grows for a different reason entirely. TrainAI is not localization sold to a retailer or a bank entering a new market. It is data annotation, human feedback and model safety testing sold to AI labs building and evaluating their own models. RWS's own description of the April trading statement names "an additional programme with an existing client and initial revenue from a new global technology client" as the drivers, the kind of customer language that describes a handful of large AI-lab contracts, not thousands of localization clients buying translated word counts.

The pending Acolad acquisition sits entirely on the Transform side of this split. Acolad's reported 2025 revenue of roughly £182m is translation and localization work for enterprise and life-sciences clients, the same category RWS is pivoting away from internally. Consolidating it adds scale and client relationships to the segment that just shrank, which is a bet that the pivot itself, not the segment, is the thing worth paying for.

What this means if you run localization strategy

Your vendor's biggest growth story may have nothing to do with your contract. If RWS, Lionbridge, Welo Global or any multi-service LSP reports strong overall growth, ask which segment produced it before assuming it reflects investment in your account. RWS's FY2026 growth came from TrainAI and Protect, not from Transform, the segment that holds the actual translation relationship with most enterprise buyers.

"Technology-first" is a pricing signal, not just a workflow change. RWS's own framing of the Transform pivot, lower revenue per word as MT and LLM output replaces human-translated volume, is the vendor-side mirror of what a localization buyer should expect on invoices: falling per-word rates, more automated post-editing, and quality assurance shifting from translation review to AI-output review. Negotiate the SLA around that shift explicitly rather than assuming "AI-powered" and "better quality" are the same claim.

Analyst leadership titles and segment economics can point in opposite directions at the same vendor. RWS and Welo Global both announced Forrester Wave Leader status for localization services in the same week RWS's own trading statement described its localization segment as shrinking. Our judgement: a Leader placement measures current capability and roadmap, not whether the category is growing inside that specific vendor's business. Ask the vendor directly what share of their revenue the localization line represents and whether it grew or shrank last year, a question their public marketing will not answer for you.

Consolidation among large LSPs is adding scale to a shrinking line, not a growing one. If RWS completes the Acolad acquisition as expected, in roughly the next two weeks from the 27 October statement, it will have bought more Transform-type revenue into a segment that just posted another organic decline. That can still make sense for RWS, as cost synergies and client-base scale, but a localization buyer evaluating RWS post-acquisition should not read the deal itself as a vote of confidence in translation demand.

RWS's full FY2026 audited results, with exact segment-level full-year growth percentages instead of the qualitative "double-digit" and "mid-single-digit" bands used in the trading statement, are due on 15 December 2026.

What would prove this wrong

The claim under test is that RWS's Transform segment, its core localization business, is shrinking organically while its AI training-data segment grows, and that this reflects a structural shift in where large LSP revenue comes from, not a one-off. This is wrong if RWS's 15 December 2026 full-year results show Transform organic constant currency revenue growth at or above zero for FY2026, rather than the "mid-single-digit decline" described in the 27 October trading statement. It is also wrong, on a longer horizon, if RWS's H1 FY2027 report (expected around June 2027, following the same cadence as the 11 June 2026 report) shows Transform OCC growth turning positive, which is what CEO Ben Faes's statement that "sales investment is intended to support improved organic growth in FY27, including in Transform technology revenue" predicts should happen.

A narrower, judgment-flagged prediction: once RWS completes the Acolad acquisition, expected within about two weeks of 27 October 2026, Transform's share of RWS group revenue will rise above the 58 percent recorded in H1 FY2026, because Acolad's revenue is almost entirely localization. If RWS's next reported segment split shows Transform's share flat or lower after the acquisition closes, that prediction was wrong.

FAQ

Is RWS's localization business growing or shrinking in 2026?

Shrinking. RWS's Transform segment, the business that actually does translation and localization, fell 7.2 percent in reported revenue and 4.6 percent on an organic constant currency basis in the six months to 31 March 2026, and RWS's 27 October 2026 year-end trading statement describes full-year organic constant currency growth in Transform as a mid-single-digit decline. The company as a whole still grew, about 3 percent organically for the full year, because its Generate and Protect segments grew faster than Transform shrank.

What is RWS's Transform segment and why is it declining?

Transform is RWS's localization segment: AI language technology paired with human linguists to adapt text, voice, video and software into other languages. It was 58 percent of group revenue in the six months to 31 March 2026 (£210.1m of £360.3m). RWS says the decline is deliberate, a pivot away from billing by human translation volume toward technology-first, machine-translation-led delivery, which RWS itself describes as reducing per-word revenue even as it tries to protect margin.

What is driving growth in RWS's Generate segment?

TrainAI, RWS's AI training-data business: data annotation, human feedback and model safety testing sold to AI labs, not translation sold to enterprises localizing products. Generate revenue rose from £68.7m to £99.4m in the six months to 31 March 2026, up 52.0 percent organic constant currency, and RWS's October 2026 trading statement describes full-year Generate growth as double-digit. Across the group, AI-related products and services were 32 percent of revenue in H1 FY2026, up from 26 percent in H1 FY2025.

Is RWS still buying Acolad, and does that change the picture?

Yes. RWS agreed in August 2026 to acquire Acogroup, Acolad's parent, and its 27 October 2026 trading statement says French regulatory and Works Council approvals have come through, with completion expected within two weeks of that statement. Acolad's 2025 revenue has been reported elsewhere at roughly £182m, almost entirely translation and localization work, which would add scale to the same Transform-type business that just posted another organic decline, not to Generate.
