Kwon Oh-hyun, Samsung's chief executive, told an annual shareholders meeting the scandal was regrettable, but the company did nothing illegal.
Five Samsung executives, including its vice chairman and founding family heir apparent Lee Jae-yong, have been indicted on bribery and other charges.
The scandal resulted in the impeachment of President Park Geun-hye earlier this month.
Calls to reform Samsung and other conglomerates are gaining momentum after Samsung, Hyundai, SK, LG and other major businesses made big donations to foundations controlled by a friend of Park's who has been charged with meddling in state affairs.

The company's image has also taken a big hit from cases of overheating and sometimes exploding batteries of its flagship Galaxy Note 7 smart phones. Samsung ended up discontinuing the product just weeks after it was launched in August.
Shin Jong-kyun, a Samsung president, promised shareholders the company will put "flawless" products through extensive safety checks. The precautions would be perfect, he said. Samsung is due to unveil the Galaxy S8 smartphone next week, its first major smartphone launch since the battery fiasco.
But the main focus of attention during today's meeting was the scandal.
Kwon, the chief executive, denied Samsung did anything unlawful in making the donations to Park's associate.
"It was a donation that was traditional and customary," Kwon said. "The auditing committee found it was executed through normal procedures."
Samsung says it will require its board of directors to approve any donations of over 1 billion won (USD 89 million) to prevent future scandals.
While shareholders were shaken by the scandal and resulting damage to the company's image, many praised the company for delivering strong results overall.
Samsung stock jumped more than 60 per cent from a year ago thanks to strong performance of its semiconductor business, which offset the damage from the Note 7 battery troubles.
