Shares of Charter Communications Inc. (CHTR) - Get Report were rising early Monday on reports that Japanese technology company SoftBank Group Corp. is interested in purchasing the cable company. 

The move comes just hours after Charter rejected an offer from SoftBank to combine with telecom company Sprint Corp. (S) - Get Report , of which SoftBank is the majority shareholder, Bloomberg reported. 

"We understand why a deal is attractive for SoftBank, but Charter has no interest in acquiring Sprint," Charter said in a statement Sunday, rejecting SoftBank's offer. 

Charter shares were up 4.83% to $388.09 per share while Sprint shares were down 1.46% to $8.10 in morning trading.
