Feb 4 (Reuters) - Aerospace supplier TransDigm Group ( TDG )

raised its annual profit forecast on Tuesday, betting on

strong demand for aftermarket parts and services from

planemakers and carriers.

The company, which supplies aircraft components such as

cockpit security systems and engine sensors for commercial and

military jets, also beat Wall Street estimates for quarterly

profit.

Demand for aircraft parts has risen as planemakers rush

to fulfill expansion plans by airlines looking to cash in on the

booming market for air travel.

However, delayed deliveries of new planes have pushed

airlines to extend the use of older aircraft, boosting orders

for profitable aftermarket parts for suppliers such as

TransDigm ( TDG ).

The Cleveland, Ohio-based company expects its 2025 profit

per share to be between $32.27 and $34.19, compared to the

previous forecast of $31.47 to $33.39.

The company, which counts planemakers Boeing ( BA ) and

Airbus among its customers, reaffirmed its annual sales

forecast of $8.75 billion to $8.95 billion.

It posted an adjusted profit of $7.83 per share for the

first quarter, beating analysts' average estimate of $7.65,

according to data compiled by LSEG.

The company's net sales for the quarter through Dec. 28 rose

12% to $2 billion, compared with expectations of $2.03 billion.
