Investor confidence in Auction Technology Group (ATG) has suffered a significant dent in 2025. A profit warning in August, followed by a substantial goodwill write-down on previous acquisitions, has reinforced the perception that growth at ATG is no longer automatically linked to predictable profitability. Although the company continues to invest strategically and expand its position in online auctions, the market has reacted in recent months primarily to disappointing margins, increasing complexity, and heightened uncertainty about the quality of previous acquisitions. However, the stock has since fallen so much that a major shareholder has made several attempts to acquire the company, but ATG is resisting this. Sharesunderten is seizing this opportunity and adding 650 ATG shares to its portfolio. Profile This British company, Auction Technology Group, traces its roots back to 1971. What began as a traditional auction service provider has evolved over the decades to match the sector’s technological development. The real transformation occurred in the 2000s, when the company increasingly focused on digitalization and online auctions. This shifted ATG from a traditional auction-related company to a technology platform that facilitates auctions without acting as an auction house itself. By bringing together platforms like LiveAuctioneers, Proxibid, The Saleroom, and Invaluable, ATG built a global network of auction houses and buyers. This network is crucial to the company’s profitability. The more listings appear on the platforms, the more attractive it becomes for buyers to join, which in turn leads to higher bids and more transactions. ATG facilitates auctions across a wide range of categories. In the art and antiques segment, this includes paintings, jewelry, coins, design objects, and collectibles. In the industrial and commercial segment, for example, machinery, construction equipment, trucks, agricultural equipment, and complete business inventories are auctioned. The revenue model consists of several components. The foundation is formed by commissions on transactions and fixed fees or subscriptions that auction houses pay for access to the platforms. In addition, ATG increasingly earns revenue from ancillary services, such as shipping, payments, and marketing services. Acquisitions ATG’s current position has been largely built through a long series of acquisitions. This acquisition strategy began relatively controlled, but has become increasingly capital-intensive and complex in recent years, eroding investor confidence. Around and shortly after the IPO in 2021, the acquisition strategy was further accelerated, with larger transactions such as LiveAuctioneers and Auction Mobility. In the 2025 fiscal year, the downside of this strategy came to light. ATG had to make a substantial goodwill write-down on previous acquisitions. A total of over $150 million was written off. This write-down had no cash flow impact, but it did confirm that part of the acquisition prices paid were no longer defensible based on the expected returns. In August 2025, ATG announced the acquisition of Chairish, an online marketplace for vintage furniture and design objects with fixed prices. Strategically, Chairish fits with the ambition to broaden its offering and appeal to buyers outside the traditional auction model. The announcement coincided with a profit warning, leading the market to view the transaction not as a logical next step, but as a risky extension at a time when confidence was already fragile. Takeover attempts by major shareholder In recent weeks, major shareholder FitzWalter Capital Partners has been in the spotlight. They made several attempts to take ATG private through successive bids. ATG rejected these attempts because the board considered the proposals insufficient and believed the bids did not adequately reflect the platform’s value and growth prospects. FitzWalter has since definitively stated that it will not submit a bid, thus ending the takeover process. Importantly, this episode clearly demonstrates that ATG is being followed not only by investors but also by parties looking at the company strategically. The fact that a major shareholder was willing to consider a bid confirms that the platform is a valuable asset in a market that remains highly fragmented globally. It is noteworthy that FitzWalter Capital purchased additional shares in early February, indicating that although the takeover bids were unsuccessful, they consider this level far too low to pass up. Results ATG operates with a split fiscal year ending on September 30. FY26 therefore covers the period from October 1, 2025, to September 30, 2026. In the Q1 trading update (through December 31, 2025), ATG reported a clear acceleration in revenue development. Revenue growth in constant currency amounted to 8.5%. This growth was primarily driven by the Arts & Antiques division, while Industrial & Commercial showed a slight decline in revenue. Chairish, which falls within Arts & Antiques, also made a good contribution to pro forma growth, with ATG explicitly stating that the benefits of becoming part of the group are starting to become apparent. At the same time, the integration remains on track, with operational synergies still moving towards an annual run rate of $8 million. ATG reported that the adjusted net debt/adjusted EBITDA ratio decreased to 2.0x at the end of December, compared to 2.2x at the end of FY25. Based on this Q1 performance, management confirmed its guidance for FY26. The company still expects pro forma revenue growth of 4–5%, with the growth being more pronounced in the first half of the year. ATG also expects an adjusted EBITDA margin of 34.5–35.5%. Management also reiterated that adjusted free cash flow remains strong and that leverage should be well below 2x by the end of FY26. Estimates The impact of the Chairish acquisition is clearly visible in the estimates for the coming years. The figures show that ATG is currently in a transition phase, with revenue growth continuing, accelerating in 2026 when the Chairish acquisition is fully factored in, but profitability is temporarily under pressure. This is a direct result of the integration of recent acquisitions, the shift toward lower-margin services, and the higher costs in the first years after an acquisition. It is expected that once the integration of acquisitions is complete and economies of scale are truly realized, ATG will once again benefit from operating leverage. Profitability is expected to increase
