'May I have some too?' 'Oh, of course — today's on the company.'

Literal

'I [also-も] receive good [question-ですか]' 'Ah, of-course not-mind [emphatic-よ], today [topic-は] company-paid [reason-だからね]'

頂いていいですか 'may I receive/have some?' — 頂く is the humble form of もらう. 会社持ち 'company-paid, on the company' — 持ち 'holding/bearing (the cost).' The second speaker is generous because the bill isn't theirs. だからね explains the reason with casual warmth.
