NEW YORK (TheStreet) -- Progressive Waste Solutions (BIN) stock is down by 6% to $38.09 in mid-afternoon trading on Tuesday, after the TreasuryDepartment proposed new tax regulations to prevent corporate tax inversions.

Waste Connections' (WCN) combination with Vaughan, Canada-based Progressive Waste is considered an inversion because it allows the waste management company to avoid U.S. taxes, the Wall Street Journal reports. The combined company's new headquarters will be in Toronto. 

Progressive Waste and Waste Connections said the proposed regulations could negatively impact less than 3% of the combined company's adjusted free cash flow during the first year, or around $625 million. 

The companies remain committed to the merger, they said in a statement. 

Allergan (AGN), which could also be affected by the proposed regulations, is also declining today.

Waste Connections stock is down by 5.59% to $60.93 in mid-afternoon trading on Tuesday.
