A statement released by Tickford indicates it is keen to keep Winterbottom and will look to "finalise discussions" in the near future.
"Tickford Racing would like to address this week’s speculation of Mark Winterbottom’s future with the team," the statement reads.
"We have enjoyed a tremendous and immensely successful partnership with Frosty over the last 13 seasons and we have been in discussion to see that partnership continue.
"Following this weekend’s event we will be meeting with Mark to finalise those discussions.
"Our shared focus remains on winning this weekend’s Supercheap Auto Bathurst 1000, a feat we achieved together in 2013.
"No further comment will be made on the matter this weekend."
Schwerkolt meanwhile declined to comment on his 2019 plans when approached by Supercars.com at Bathurst.
