Auction Technology Group Posts Strong H1 Results, Upgrades FY Guidance

Auction Technology Group’s half-year results are a classic case of “better underneath than the statutory headline suggests”. The market-friendly bit is straightforward: underlying growth was solid, cash generation was strong, debt came down, and management has upgraded full-year guidance. That is usually a decent mix for shareholders.

The trickier part is that reported profit looks messy. ATG swung to a small loss after tax and reported operating profit more than halved, but that was largely driven by exceptional costs, higher share-based payments and acquisition-related accounting after buying Chairish. So if you only looked at the statutory bottom line, you would miss the more encouraging story.

Auction Technology Group H1 2026 results: the numbers that matter most

Metric	HY26	HY25	Change
Revenue	$126.1 million	$89.0 million	+41.7% reported
Pro forma constant currency revenue growth	–	–	+7.9%
Adjusted EBITDA	$42.7 million	$38.5 million	+10.9%
Adjusted EBITDA margin	33.9%	43.3%	-9.4 percentage points reported
Operating profit	$7.0 million	$15.0 million	-53.3%
Loss/profit after tax	$(0.4) million	$7.0 million	Down
Adjusted diluted EPS	19.9 cents	19.0 cents	+4.7%
Adjusted free cash flow	$26.5 million	$14.2 million	+86.6%
Adjusted net debt	$152.0 million	$106.5 million	Higher year on year, but down from $174.0 million at FY25

The big number to focus on is the 7.9% pro forma constant currency revenue growth. That strips out currency swings and treats Chairish as if it had been owned in both periods, which gives a cleaner view of the underlying business.

That matters because the reported 41.7% revenue growth is flattered by the Chairish acquisition. There is nothing wrong with that, but investors should separate acquisition boost from genuine like-for-like momentum.

Why ATG upgraded FY26 guidance and why investors should care

Management has nudged up full-year guidance, and that is the clearest sign this was a better-than-expected half. ATG now expects revenue growth of 5-6% on a constant currency, pro forma basis, up from previous guidance of 4-5%.

It also expects an adjusted EBITDA margin of 34.5-35.5% for the full year, continued strong adjusted free cash flow, and leverage well below 2x by year end. In plain English, the business is growing a bit faster than planned, still converting profit into cash, and getting less financially stretched.

The company also said trading in April was in line with expectations. That is not spectacularly exciting, but it is reassuring when a business upgrades guidance and then immediately says the new quarter has not gone off the rails.

Arts and Antiques is doing the heavy lifting for Auction Technology Group

The standout division was Arts & Antiques, or A&A. Revenue here rose 12.5% on a pro forma constant currency basis, with GMV – gross merchandise value, meaning the total value of goods sold on the platform – up 5% to $0.5 billion.

Take rate, which is the percentage of GMV ATG turns into revenue, improved in A&A to 17.7%, up 1 percentage point. That is a strong sign because it means ATG is not just selling more stuff, it is monetising each dollar of sales better too.

The company credits that to value-added services, especially atgShip, its integrated shipping solution. Over 1,400 auction houses were onboarded on atgShip by the end of March 2026, up from around 1,000 at FY25, and management says first-time winning bidders using atgShip have a 20% higher repeat purchase rate than those who do not.

That is the kind of detail I like in a results statement. It suggests shipping is not just an extra fee bolted on top, but something that improves the customer experience and helps drive repeat business.

LiveAuctioneers also looks to be responding to ATG’s product work. The company said improvements there generated an 8.2% increase in GMV and 9.4% growth in items sold, helped by better search, AI-driven recommendations and smoother buyer journeys.

Industrial and Commercial remains the problem child

There is a softer side to this update, and it sits in Industrial & Commercial, or I&C. Revenue fell 1.8% on a pro forma constant currency basis, with GMV down 2% to $1.3 billion.

The reasons are not especially comforting. ATG pointed to weak agricultural markets, third-party white label adoption by some sellers, and auction house consolidation. Agricultural GMV was down 27% in the period, which is a hefty drag.

The good news is that retention still looks strong. Over 80% of GMV comes from returning buyers and 90% of GMV comes from sellers who have been with the platform for more than five years, which tells you this is not a broken franchise.

But the division clearly needs work. The Proxibid replatforming is progressing and the first auction house is now in testing, but this is still a “show me” story rather than a “problem solved” story.

Margins, profit and the awkward gap between adjusted and reported numbers

This is where investors need a bit of care. Adjusted EBITDA rose 10.9% to $42.7 million, but reported operating profit fell 53.3% to $7.0 million and the group posted a loss after tax of $(0.4) million.

The main reason is that adjusted figures exclude items management says do not reflect underlying trading, including amortisation of acquired intangibles, exceptional operating items, share-based payment expense and some finance items. Those adjustments totalled $29.9 million at the operating profit level in HY26, which is large.

Some of that is understandable. Chairish integration costs, restructuring costs and project costs are not likely to recur every half, but investors should still keep an eye on how often “exceptional” costs turn up.

Margins also need context. Reported adjusted EBITDA margin fell to 33.9% from 43.3%, mainly because Chairish is lower margin and shipping revenue is also lower margin. On a pro forma basis, though, margin actually improved by 0.6 percentage points, which is a lot more encouraging.

Cash flow, debt reduction and possible shareholder returns

This was one of the strongest parts of the release. Adjusted free cash flow nearly doubled to $26.5 million, while adjusted operating cash flow conversion was 85%, up from 84% a year earlier.

That cash helped bring adjusted net debt down to $152.0 million from $174.0 million at FY25, with leverage falling to 1.8x from 2.2x. That is important because a debt-heavy growth story can turn nasty quickly if trading wobbles, but ATG is moving the other way.

More interestingly, the board said it will consider capital allocation towards the end of the year given rapidly reducing leverage. The company later said it will consider options for returning excess capital to shareholders as leverage approaches around 1.5x. No dividend has been proposed, but the door is clearly opening to some form of shareholder return if trading holds up.

Chairish integration is helping growth, but it is still diluting margins

Chairish was profitable in the first half, which is a useful milestone. ATG has already realised $3.0 million of operational synergies and remains on track for a full run-rate of $8.0 million in FY27, with $6.0 million expected in FY26.

That said, Chairish is still part of the reason group margins look lower. So the acquisition is currently a balance of positive revenue contribution and synergy progress against some margin dilution. So far, that trade-off looks acceptable, especially now the business is profitable.

My take on Auction Technology Group shares after this H1 update

On balance, this is a positive update. The upgrade to guidance, strength in A&A, good cash generation, falling leverage and early signs of product improvements working all point in the right direction.

The negatives are real too. I&C remains sluggish, reported profits are weak, and there is still a chunky gap between statutory and adjusted numbers. Investors should not ignore that.

Still, if you are judging the health of the business rather than just the accounting noise, ATG looks to have had a good half. The business now needs to prove two things in the second half: that A&A momentum is sustainable, and that I&C can at least stop drifting backwards. If it manages both, this upgraded guidance may not be the last one.
