The Joint Corp. increases stock repurchase program by $12 million.

The Joint Corp., the nation's largest chiropractic care provider, has authorized an additional $12 million for its stock repurchase program. The move follows the completion of the first $5 million tranche, which resulted in the buyback of 540,000 shares. The company believes its asset-light franchise model, growth opportunity, and long-term valuation are not fully recognized in its current share price.
