ATG FY25 Trading Update: In-Line Performance with Goodwill Impairment

ATG FY25 trading update – steady delivery, with a goodwill knock

Auction Technology Group’s pre-close update for the year to 30 September 2025 lands broadly in line with its revised guidance. Revenue growth picked up in the second half and adjusted EBITDA margins look solid, but investors should be prepared for a non-cash goodwill impairment.

The FY26 outlook is pegged to current market expectations, and leverage is expected to trend lower through next year. Full-year results will drop on Wednesday 26 November 2025.

Revenue picture – modest underlying growth, bolstered by Chairish

ATG says full-year revenue growth excluding Chairish was up over 4%, with H1 at 3.4%, implying a better H2 pace. Including Chairish, group revenue is expected to be up around 9%. That is a useful step-up, though it reflects mix as well as organic execution.

Management highlights good progress in Value Added Services, specifically atgAMP, atgPay and particularly atgShip. These are add-on services around auctions such as payments and shipping that can lift take-rate and stickiness. Initial trading for Chairish has been in line with expectations.

Profitability and margins – resilience at 42%-43% excluding Chairish

Adjusted EBITDA margin is expected to land between 42% and 43% excluding Chairish, in line with the revised guide. For clarity, adjusted EBITDA is a profit measure before interest, tax, depreciation and amortisation, adjusted for certain items to show underlying performance.

That level of margin signals a capital-light marketplace model still throwing off good cash, even as ATG invests in services that deepen monetisation. The update does not quote a group-wide margin including Chairish.

Goodwill impairment – non-cash, but not nothing

ATG expects to book a non-cash goodwill impairment for FY25. The drivers are higher discount rates, macroeconomic conditions, and the impact of the 4 August trading announcement. A goodwill impairment reduces the carrying value of acquired assets on the balance sheet when future cash flow assumptions are lowered.

Why it matters: it does not hit cash or adjusted EBITDA, but it does acknowledge that the valuation underpin for past deals has softened. It can weigh on sentiment, and it often prompts investors to revisit growth and return assumptions. The size of the impairment is not disclosed.

Leverage and cash – c.2.2x now, expected below 2x by FY26 end

Adjusted net debt to adjusted EBITDA is expected to be around 2.2x at year end, supported by good cash generation. This ratio, per the Senior Facilities Agreement, is ATG’s key leverage yardstick.

Management guides that adjusted net leverage should fall to well below 2x by the end of FY26. If delivered, that gives headroom for optionality and reduces balance sheet risk as rates and discount factors remain elevated.

FY26 outlook – tracking current market expectations

ATG pins FY26 to current analyst ranges. That sets a clear yardstick for investors to measure progress quarter by quarter.

Metric	FY2025 expectations	FY2026 expectations
Revenue	US$185.4m – US$187.2m [mid-point US$186.3m]	US$238.0m – US$245.7m [mid-point US$241.3m]
Adjusted EBITDA	US$75.1m – US$76.0m [mid-point US$75.8m]	US$82.9m – US$87.0m [mid-point US$85.5m]
Adjusted EBITDA margin	42%-43% excluding Chairish	Not disclosed
Leverage	c.2.2x adjusted net debt to adjusted EBITDA	Well below 2x expected by FY26 year end
Revenue growth commentary	Ex-Chairish up over 4%; including Chairish up c.9%	In line with current market expectations

Strategic execution – value added services doing the heavy lifting

The growth call-outs around atgAMP, atgPay and atgShip suggest ATG is leaning into higher value, higher margin services that can compound over time. atgShip in particular is highlighted as a strong contributor. This matters because marketplace take-rate expansion can drive revenue growth even if lot volumes are choppy.

ATG operates across Arts & Antiques and Industrial & Commercial, powering ten branded auction and list price marketplaces. It facilitates the sale of more than 24 million unique secondary items each year with a value of over US$13 billion. That scale gives it a broad funnel to cross-sell services.

What to watch on results day – 26 November 2025

• Goodwill impairment size – the quantum and which cash-generating units are affected.
• Chairish integration and contribution – revenue share, margins, and any updated synergy talk.
• Value Added Services trajectory – growth rates for atgAMP, atgPay, atgShip and their impact on take-rate.
• Leverage bridge – the cash flow drivers that get leverage well below 2x by FY26 end.
• Any colour on macro sensitivity – especially across A&A versus I&C end markets.

Josh’s take – balanced, with an eye on the impairment

On the positives, ATG has delivered to its reset, with H2 revenue momentum improving and margins holding firm at 42%-43% excluding Chairish. Value Added Services are clearly gaining traction, and leverage is moving in the right direction with good cash generation.

On the negatives, a goodwill impairment is never a great headline. It underlines higher discount rates and a slightly tougher macro backdrop, and it follows the 4 August trading update that trimmed expectations. The update does not quantify the charge, which leaves some uncertainty until results day.

Net-net, this is a steady pre-close. FY26 being in line with market expectations helps anchor the story, but the market will want proof that service-led growth can keep margins robust while leverage trends below 2x. If ATG can show continued uplift from atgShip, atgPay and atgAMP, and quantify an impairment that is digestible, the equity case looks intact.
