Mark Sickles

Mark Sickles is the Secretary of Finance for the Commonwealth of Virginia, serving in Governor Glenn Youngkin's cabinet. On or around 22 May 2026, Sickles disclosed to the Senate Finance and Appropriations Committee that Compass Datacenters had halted its search for two sites in Greensville County and Emporia, abandoning the searches before filing any planning application. The sole stated reason was uncertainty over Virginia's data-centre sales and use tax exemption, whose future is contested between the Senate (seeking to end it by 2026) and the House (seeking to extend it to 2035).

As Secretary of Finance, Sickles oversees the state's fiscal management and revenue operations. His role placed him in the awkward position of conveying private corporate decisions to the legislature as evidence in a live budget dispute. The Compass disclosure is significant because it is the first on-record attribution of a specific operator's decision to the abatement standoff, lending weight to industry warnings that tax uncertainty is a real site-selection deterrent rather than negotiating posture.

Sickles represents the executive branch's position in a dispute that is primarily between the two chambers of the legislature. His disclosure to the Senate Finance Committee, chaired by the abatement's most prominent opponent, was effective evidence in the chamber's favour — illustrating the direct economic cost of the stand-off in a way that aggregate revenue projections could not.
