What Has Changed Since the Last Record

Andersen Group (NYSE:ANDG), the tax, valuation and advisory firm, has kept climbing since its earlier highs, and the fresh driver is the pace of acquisitions. On October 5 it completed a UK acquisition. On October 7 it announced three deals in Italy, the Netherlands and South Africa. On October 15 it closed four consulting acquisitions, including SPR, BD Emerson, Daniels Consulting Group and Zenger Folkman, and said it had signed 19 agreements in 2026 worth about USD 190 million of annualised revenue. On November 2 it announced three more closings, and the stock set a new high that day, trading up to USD 67.26 before the screen's USD 67.46 on November 4. For a firm guiding to revenue of about USD 1.0 billion, acquired revenue of about USD 190 million is a large addition, about 19% at the top of the range, our own arithmetic. The company had about 2,690 employees and served about 13,500 client groups at mid-year, so each acquisition adds both people and client relationships to the platform.

Why Investors Pay Up for the Roll-Up

Professional services roll-ups are valued on revenue growth and Margin expansion. Second-quarter revenue rose 23.7% to USD 217.7 million, and adjusted Net Income was USD 39.0 million, although the company recorded a GAAP net loss of USD 10.1 million. The gap between the two shows how much non-cash and deal costs weigh on reported profit. Full-year guidance calls for adjusted EBITDA of USD 225 million to USD 250 million. The screen shows a P/E of 7.88 on EPS of USD 8.56, but those figures conflict with the reported quarterly loss and should not be relied on. A better gauge is market value of about USD 7.62 billion against guided revenue near USD 1.0 billion, about 7.6 times sales, our own arithmetic. That premium assumes acquisitions keep adding growth at attractive prices. If acquired firms can be moved onto common systems and branding, margins should improve over time, which is the core of the Investment case.

Risks and What to Watch

Integration is the main risk. Closing many deals in a few weeks across several countries strains systems, culture and partner retention, and professional services firms depend on their people. Supply of stock is another factor: an August secondary offering sold 4,284,457 shares at USD 44.00, and further sales by early holders are possible. The November 5 market sell-off adds a near-term test. Investors in Andersen Group (NYSE:ANDG) should watch the November 12 report for organic growth, the revenue contribution from acquisitions, any change to full-year guidance and whether adjusted margins hold. Any comment on the acquisition pipeline for 2027 will also matter, since the valuation assumes the deal pace continues.

Where Things Stand

Andersen Group set a fresh record as it kept closing deals, adding three acquisitions on November 2 to a 2026 total of about USD 190 million of annualised revenue signed. Revenue growth of 23.7% in the second quarter supports the roll-up story, while a GAAP loss and a high multiple of sales raise the bar. The November 12 results are the next test.
