July 15 (Reuters) - The following bids, mergers,

acquisitions and disposals were reported by 1330 GMT on Monday:

** Macy's has ended its buyout discussions with

Arkhouse Management and Brigade Capital, saying that their

raised offer lacked the certainty of financing and did not

provide compelling value, sending its shares down 15% in early

trading.

** Cleveland-Cliffs ( CLF ) said it will buy Canadian peer

Stelco Holdings ( STZHF ) for C$3.85 billion ($2.8 billion),

marking its first acquisition since a failed bid for rival U.S.

Steel last year.

** Dutch company Yandex NV ( YNDX ) said it had finalised

the divestment of its Russia-based technology assets to a

consortium of Russian investors in a cash and shares deal worth

around $5.4 billion.

** European aerospace groups Airbus and Thales

are exploring a tie-up of at least part of their space

activities, two industry sources said, confirming a report by

French business paper La Tribune.

** Google parent Alphabet is in advanced talks to

acquire cybersecurity startup Wiz for roughly $23 billion, a

person familiar with the matter said on Sunday, in a deal that

would represent the technology giant's biggest acquisition ever.
