Kent have announced operating profits of £188,000 for 2011.
Having suffered losses of nearly £600,000 in 2010, they invested money from the sale of land at their Canterbury home in stadium facilities.
Dressing rooms were also enlarged and permanent floodlights were installed.
Kent chairman George Kennedy said: "I'm delighted the financial benefits of the work carried out at the St Lawrence Ground in the last year are starting to show in our results."
He continued: "After taking account taxation adjustments and interest charges, the overall profit was £379,000."
The County Championship side, who finished eighth in Division Two last season, have also invested money in new building work and plan to construct a new hotel.
"We now have conferencing and event facilities which make Kent Cricket a year-round business, in effect making the ground 'fit for purpose'," Kennedy continued.
"In addition, the club's plan for hotel development remains an important part of our future strategy and it is hoped that this too will progress in the near future.
"These financial results, coupled with the recent appointment of Jimmy Adams as head coach gives me great confidence in the future of Kent Cricket."
