Pyxis Advisory Group, an advisory firm focused on the industrial sector, has acquired Catule Consulting. The deal, effective Sept. 1, 2025, integrates Catule’s principals, Josh Grahmann and Silas Aday, into the Pyxis leadership team. Both will join the Houston office as Managing Directors, leading the firm’s Upstream and Oilfield Services industry verticals.

The acquisition appears to be a strategic move by Pyxis to deepen its service capabilities for clients navigating business transformations within the energy sector. Pyxis currently offers services that include merger and acquisition support, commodities trading and digital transformation. By bringing in the leadership of Catule, the firm adds specialized expertise in oil and gas consulting.

"We've known and worked alongside Josh and Silas for decades and have seen firsthand their ability to guide clients through complex and strategic transformations," said Matt Flanagan, a Partner at Pyxis Advisory Group. "Their expertise aligns perfectly with our mission at Pyxis."

The new managing directors bring extensive experience to the firm. Josh Grahmann has over 27 years in consulting, focusing on business integration, technology implementation, and process improvement for major companies in the oil and gas industry. Silas Aday has nearly 25 years of experience in the Upstream and Oilfield Services sectors, with a specialization in systems implementation, data management, and asset management for clients with large equipment fleets.

"Having collaborated with Pyxis in the past, I know the value we can create together," Grahmann stated. "By combining our expertise, we'll deliver practical solutions that drive efficiency, spark innovation, and support clients through their challenges."

The integration of the two firms is presented as a natural extension of a long-standing professional relationship. Aday noted that he and Grahmann have collaborated with Pyxis on numerous client projects over the years, suggesting a preexisting synergy between the teams. This acquisition formalizes that partnership, aiming to provide more integrated solutions to the industrial market.
