Cumulus Media joined the radio industry’s third quarter advertising rebound Wednesday afternoon, reporting a 21.0% revenue increase to $237.7 million for the three months ended Sept. 30, compared to $196.4 million in the same period one year ago.

Spot sales at the company’s radio station group improved 12.2% to $122.0 million, up from $108.7 million one year earlier. The Westwood One network division did better, with billings up 21.0% to $63.9 million versus $52.8 million in Q3 2020. Digital, once again, was the main growth driver, surging to $33.4 million, a 67.1% increase over $19.9 million one year ago. That means digital now delivers nearly half as much to the company’s topline as does Westwood One. Revenue classified as “other” jumped 23.9% to $18.5 million from $14.9 million.

Cumulus reported net income of $27.4 million and adjusted EBITDA (earnings before interest, taxes, depreciation and amortization of $45.8 million.

CEO Mary Berner says the results “exceeded expectations across the board,” even with the ongoing effects of COVID-19. “This performance is yet another strong example of the continuing success of our evolution from a one-dimensional radio company to a multi-dimensional, audio-first media company,” Berner said in a press release ahead of the company’s quarterly call with investors. “We see significant and continued upside potential and multiple drivers of shareholder value, which include additional radio market recovery, several fast-growing digital business lines, attractive free cash flow conversion, a strong balance sheet and liquidity profile, and substantial optionality regarding future capital allocation.”
