US LEC (Nasdaq: CLEC) won’t announce its year-end earnings report until Feb. 26. But the regional telecommunications provider said on Thursday that it will report its fourth consecutive quarter of positive cash growth.

Aaron Cowell, president and chief executive officer of US LEC, attributed the performance to several factors, including growth of its customer base. The company now serves more than 15,000 business customers, and its recent acquisition of Pennsylvania-based Fastnet will push that number past 17,000.

US LEC has also reduced its debt by $6 million through the private placement of $10 million.

Its stock was trading at $7.06 in midday trading today. That’s off a 52-week high of $8.60, but a far cry from the year-low of $1.90.
