is
registered
under
the
Investment
Company
Act
of
1940
(1940
Act)
as
an
open-end
management
investment
company.
The Fund
follows
the
accounting
and
reporting
guidance
in
Financial
Accounting
Standards
Board
(FASB)
Accounting
Standards
Codification
Topic
946,
Financial

guidance
in
U.S.
Generally
Accepted
Accounting
Principles
(U.S.
GAAP),
including,
but
not
limited
to,
ASC
946.
The
Fund
offers five
classes
of
shares:
Class
A,
Class
C,
Class
R,
Class
R6
and
Class
Y.
Class
C
shares
automatically
convert
to
Class
A
shares
on
a
monthly
basis,
after
they
have
been
held
for
8
years.
Each
class
of
shares
may
differ
by
its
initial
sales
load,
contingent
deferred
sales
charges,
voting
rights
on
matters
affecting
a
single
class,
its
exchange
privilege
and
fees
due
to
differing
arrangements
for
distribution
and

fees.
Effective
September
5,
2024,
all
Class
B
shares
were
converted
to
Class
A.
The
following
summarizes
the Fund's
significant
accounting
policies.
a.
Financial
Instrument
Valuation
The
Fund's
investments
in
financial
instruments
are
carried
at
fair
value
daily.
Fair
value
is
the
price
that
would
be
received
to
sell
an
asset
or
paid
to
transfer
a
liability
in
an
orderly
transaction
between
market
participants
on
the
measurement
date.
The
Fund
calculates
the
net
asset
value
(NAV)
per
share
each business
day as
of
4
p.m.
Eastern
time
or
the
regularly
scheduled
close
of
the
New
York
Stock
Exchange
(NYSE),
whichever
is
earlier.
Under
compliance
policies
and
procedures
approved
by
the Trust's
Board
of
Trustees
(the
Board),
the
Board
has
designated
the
Fund's
investment
manager
as
the
valuation
designee
and
has
responsibility
for
oversight
of
valuation.
The
investment
manager
is
assisted
by
the
Fund's
administrator
in
performing
this
responsibility,
including
leading
the
cross-
functional
Valuation
Committee
(VC).
The
Fund
may
utilize
independent
pricing
services,
quotations
from
securities
and
financial
instrument
dealers,
and
other
market
sources
to
determine
fair
value.
Equity
securities
and
derivative
financial instruments listed
on
an
exchange
or
on
the
NASDAQ
National
Market
System
are
valued
at
the
last
quoted
sale
price
or
the
official
closing
price of
the
day,
respectively. Foreign
equity
securities
are
valued
as
of
the
close
of
trading
on
the
foreign
stock
exchange
on
which
the
security
is
primarily
traded,
or
as
of
4
p.m.
Eastern
time.
The
value
is
then
converted
into
its
U.S.
dollar
equivalent
at
the
foreign
exchange
rate
in
effect
at
4
p.m.
Eastern
time
on
the
day
that
the
value
of
the
security
is
determined.
Over-the-counter
(OTC)
securities
are
valued
within
the
range
of
the
most
recent
quoted
bid
and
ask
prices.
Securities
that
trade
in
multiple
markets
or
on
multiple
exchanges
are
valued
according
to
the
broadest
and
most
representative
market.
Certain
equity
securities
are
valued
based
upon
fundamental
characteristics
or
relationships
to
similar
securities.
Debt
securities
generally
trade
in
the OTC
market
rather
than
on
a
securities
exchange.
The
Fund's
pricing
services
use
multiple
valuation
techniques
to
determine
fair
value.
In
instances
where
sufficient
market
activity
exists,
the
pricing
services
may
utilize
a
market-based
approach
through
which
quotes
from
market
makers
are
used
to
determine
fair
value.
In
instances
where
sufficient
market
activity
may
not
exist
or
is
limited,
the
pricing
services
also
utilize
proprietary
valuation
models
which
may
consider
market
characteristics
such
as
benchmark
yield
curves,
credit
spreads,
estimated
default
rates,
anticipated
market
interest
rate
volatility,
coupon
rates,
anticipated
timing
of
principal
repayments,
underlying
collateral,
and
other
unique
security
features
in
order
to
estimate
the
relevant
cash
flows,
which
are
then
discounted
to
calculate
the
fair
value.
Investments
in open-end mutual
funds
are
valued
at
the
closing
NAV.
Certain
derivative
financial
instruments
trade
in
the
OTC
market.
The
Fund's
pricing
services
use
various
techniques
including
industry
standard
option
pricing
models
and
proprietary
discounted
cash
flow
models
to
determine
the
fair
value
of
those
instruments.
The
Fund's
net
benefit
or
obligation
under
the
derivative
contract,
as
measured
by
the
fair
value
of
the
contract,
is
included
in
net
assets.
The
Fund
has
procedures
to
determine
the
fair
value
of
financial
instruments
for
which
market
prices
are
not
reliable
or
readily
available.
Under
these
procedures,
the Fund
primarily
employs
a
market-based
approach
which
may
use
related
or
comparable
assets
or
liabilities,
recent
transactions,
market
multiples,
and
other
relevant
information
for
the
investment
to
determine
the
fair
value
of
the
investment.
An
income-based
valuation
approach
may
also
be
used
in
which
the
anticipated
future
cash
flows
of
the
Putnam
Sustainable
Leaders
Fund

franklintempleton.com
Semiannual
Report
investment
are
discounted
to
calculate
fair
value.
Discounts
may
also
be
applied
due
to
the
nature
or
duration
of
any
restrictions
on
the
disposition
of
the
investments.
Due
to
the
inherent
uncertainty
of
valuations
of
such
investments,
the
fair
values
may
differ
significantly
from
the
values
that
would
have
been
used
had
an
active
market
existed.
Trading
in
securities
on
foreign
securities
stock
exchanges
and
OTC
markets
may
be
completed
before
4
p.m.
Eastern
time.
In
addition,
trading
in
certain
foreign
markets
may
not
take
place
on
every
Fund's
business
day. Events
can occur
between
the
time
at
which
trading
in
a
foreign
security
is
completed
and
4
p.m.
Eastern
time
that
might
call
into
question
the
reliability
of
the
value
of
a
portfolio
security
held
by
the
Fund.
As
a
result,
differences
may
arise
between
the
value
of
the
Fund's
portfolio
securities
as
determined
at
the
foreign
market
close
and
the
latest
indications
of
value
at
4
p.m.
Eastern
time. In
order
to
minimize
the
potential
for
these
differences,
an
independent
pricing
service
may
be
used
to
adjust
the
value

at

p.m.
Eastern
time.
At
December
31,
2025,
certain
securities
may
have
been
fair
valued
using
these
procedures,
in
which
case
the
securities
were

When
the
last
day
of
the
reporting
period
is
a
non-business
day,
certain
foreign
markets
may
be
open
on
those
days
that
the
Fund's
NAV
is
not
calculated,
which
could
result
in
differences
between
the
value
of
the
Fund's
portfolio
securities
on
the
last
business
day
and
the
last
calendar
day
of
the
reporting
period.
Any
security
valuation
changes
due
to
an
open
foreign
market
are
adjusted
and
reflected
by
the
Fund
for
financial
reporting
purposes.
b.
Foreign
Currency
Translation
Portfolio
securities
and
other
assets
and
liabilities
denominated
in
foreign
currencies
are
translated
into
U.S.
dollars
based
on
the
exchange
rate
of
such
currencies
against
U.S.
dollars
on
the
date
of
valuation.
The
Fund
may
enter
into
foreign
currency
exchange
contracts
to
facilitate
transactions
denominated
in
a
foreign
currency.
Purchases
and
sales
of
securities,
income
and
expense
items
denominated
in
foreign
currencies
are
translated
into
U.S.
dollars
at
the
exchange
rate
in
effect
on
the
transaction
date.
Portfolio
securities
and
assets
and
liabilities
denominated
in
foreign
currencies
contain
risks
that
those
currencies
will
decline
in
value
relative
to
the
U.S.
dollar.
Occasionally,
events
may
impact
the
availability
or
reliability
of
foreign
exchange
rates
used
to
convert
the
U.S.
dollar
equivalent
value.
If
such
an
event
occurs,
the
foreign
exchange
rate
will
be
valued
at
fair
value
using
procedures
established
and
approved
by
the
Board.
The
Fund
does
not
separately
report
the
effect
of
changes
in
foreign
exchange
rates
from
changes
in
market
prices
on
securities
held.
Such
changes
are
included
in
net
realized
and
unrealized
gain
or
loss
from
investments
in
the
Statement of
Operations.
Realized
foreign
exchange
gains
or
losses
arise
from
sales
of
foreign
currencies,
currency
gains
or
losses
realized
between
the
trade
and
settlement
dates
on
securities
transactions
and
the
difference
between
the
recorded
amounts
of
dividends,
interest,
and
foreign
withholding
taxes
and
the
U.S.
dollar
equivalent
of
the
amounts
actually
received
or
paid.
Net
unrealized
foreign
exchange
gains
and
losses
arise
from
changes
in
foreign
exchange
rates
on
foreign
denominated
assets
and
liabilities
other
than
investments
in
securities
held
at
the
end
of
the
reporting
period.
c.
Derivative
Financial
Instruments
The
Fund invested
in
derivative
financial
instruments
in
order
to
manage
risk
or
gain
exposure
to
various
other
investments
or
markets.
Derivatives
are
financial
contracts
based
on
an
underlying
or
notional
amount,
require
no
initial
investment
or
an
initial
net
investment
that
is
smaller
than
would
normally
be
required
to
have
a
similar
response
to
changes
in
market
factors,
and
require
or
permit
net
settlement.
Derivatives
contain
various
risks
including
the
potential
inability
of
the
counterparty
to
fulfill
their
obligations
under
the
terms
of
the
contract,
the
potential
for
an
illiquid
secondary
market,
and/or
the
potential
for
market
movements
which
expose
the
Fund
to
gains
or
losses
in
excess
of
the
amounts
shown
in
the
Statement
of
Assets
and
Liabilities.
Realized
gain
and
loss
and
unrealized
appreciation
and
depreciation
on
these
contracts
for
the
period
are
included
in
the
Statement
of
Operations.
Derivative
counterparty
credit
risk
is
managed
through
a
formal
evaluation
of
the
creditworthiness
of
all
potential
counterparties.

Fund

to
counterparty
credit
risk
on
OTC
derivatives,
whenever
possible,
by
entering
into
International
Swaps
and
Derivatives
Association
(ISDA)
master
agreements
with
certain
counterparties.
These
agreements
contain
various
provisions,
including
but
not
limited
to
collateral
requirements,
events
of
default,
or
early
termination.
Termination
events
applicable
to
the
counterparty
include
certain
deteriorations
in
the
credit
quality
of
the
counterparty.
Termination
events
applicable
to
the
Fund
include
failure
of
the
Fund
to
maintain
certain
net
asset
levels
and/or
limit
the
decline
in
net
assets
over
various
periods
of
time.
In
the
event
of
default
or
early
termination,
the
ISDA
master
agreement
gives
the
non-defaulting
party
the
right
to
net
and
close-out
all
transactions
traded,
whether
or
not
arising
under
the
ISDA
agreement,
to
one
net
amount
payable
by
one
counterparty
to
the
other.
However,
absent
an
event
of
default
or
early
termination,
OTC
derivative
assets
and
liabilities
are
presented
gross
and
not
offset
in
the
Statement
of
Assets
and
Liabilities.
Early
termination
by
the
counterparty
may
result
in
an
immediate
payment
by
the
Fund
of
any
net
liability
owed
to
that
counterparty
under
the
ISDA
agreement.
At
December
31,
2025,
the
Fund
had
OTC
derivatives
in
a
net
liability
position
of
$3,131,728
and
the
aggregate
value
of
collateral
pledged
for
such
contracts
was
$2,893,261.
Collateral
requirements
differ
by
type
of
derivative.
Collateral
or
initial
margin
requirements
are
set
by
the
broker
or
exchange
clearing
house
for
exchange
traded
and
centrally
cleared
derivatives.
Initial
margin
deposited
is
held
at
the
exchange
or
at
the
broker and
can
be
in
the
form
of
cash
and/or
securities.
For
OTC
derivatives
traded
under
an
ISDA
master
agreement,
posting
of
collateral
is
required
by
either
the
Fund
or
the
applicable
counterparty
if
the
total
net
exposure
of
all
OTC
derivatives
with
the
applicable
counterparty
exceeds
the
minimum
transfer
amount,
which
typically
ranges
from
$100,000
to
$250,000,
and
can
vary
depending
on
the
counterparty
and
the
type
of agreement.
Generally,
collateral
is
determined
at
the
close
of
Fund
business
each
day
and
any
additional
collateral
required
due
to
changes
in
derivative
values
may
be
delivered
by
the
Fund
or
the
counterparty
the
next
business
day,
or
within
a
few
business
days.
Collateral
pledged
and/or
received
by
the
Fund
for
OTC
derivatives,
if
any,
is
held
in
segregated
accounts
with
the
Fund's
custodian/counterparty
broker
and
can
be
in
the
form
of
cash
and/or
securities.
Unrestricted
cash
may
be
invested
according
to
the
Fund's
investment
objectives.
To
the
extent
that
the
amounts
due
to
the
Fund
from
its
counterparties
are
not
subject
to
collateralization
or
are
not
fully
collateralized,
the
Fund
bears
the
risk
of
loss
from
counterparty
non-performance.
The
Fund entered
into
OTC
forward
exchange
contracts
primarily
to
manage
and/or
gain exposure
to
certain
foreign
currencies.
A
forward
exchange
contract
is
an
agreement
between
the
Fund
and
a
counterparty
to
buy
or
sell
a
foreign
currency at
a
specific
exchange
rate
on
a
future
date.
Forward
exchange
contracts
outstanding
at
period
end,
if
any,
are
listed
in
the
Fund's
Schedule
of
Investments.
See
Note
8 regarding
other
derivative
information.
d.
Income
and
Deferred
Taxes
It
is the Fund's
policy
to
qualify
as
a
regulated
investment
company
under
the
Internal
Revenue
Code. The Fund
intends
to
distribute
to
shareholders
substantially
all
of
its
taxable
income
and
net
realized
gains
to
relieve
it
from
federal
income
and if
applicable,
excise
taxes.
As
a
result,
no
provision
for
U.S.
federal
income
taxes
is
required.
The Fund
may
be
subject
to
foreign
taxation
related
to
income
received,
capital
gains
on
the
sale
of
securities
and
certain
foreign
currency
transactions
in
the
foreign
jurisdictions
in
which
it
invests.
Foreign
taxes,
if
any,
are
recorded
based
on
the
tax
regulations
and
rates
that
exist
in
the
foreign
markets
in
which
the
Fund
invests.
When
a
capital
gain
tax
is
determined
to
apply,
the
Fund
records
an
estimated
deferred
tax
liability
in
an
amount
that
would
be
payable
if
the
securities
were
disposed
of
on
the
valuation
date.
The Fund
may
recognize
an
income
tax
liability
related
to
its
uncertain
tax
positions
under
U.S.
GAAP
when
the
uncertain
tax
position
has
a
less
than
50%
probability
that
it
will
be
sustained
upon
examination
by
the
tax
authorities
based
on
its
technical
merits.
As
of
December
31,
2025, the Fund
has
determined
that
no
tax
liability
is
required
in
its
financial
statements
related
to
uncertain
tax
positions
for
any
open
tax
years
(or
expected
to
be
taken
in
future
tax
years).
The
Fund's
federal
and
state
income
and
federal
excise
tax
returns
for
the
prior
three
fiscal
years
are
subject
to
examination
by
the
Internal
Revenue
Service
and
state
departments
of
revenue.

e.
Security
Transactions,
Investment
Income,
Expenses
and
Distributions
Security
transactions
are
accounted
for
on
trade
date.
Realized
gains
and
losses
on
security
transactions
are
determined
on
a
specific
identification basis.
Interest
income
(including
interest
income
from
payment-in-kind
securities,
if
any)
and
estimated
expenses
are
accrued
daily.
Amortization
of
premium
and
accretion
of
discount
on
debt
securities
are
included
in
interest
income.
Dividend
income
is recorded
on
the
ex-dividend
date
except
for
certain
dividends
from
securities
where
the
dividend
rate
is
not available.
In
such
cases,
the
dividend
is
recorded
as
soon
as
the
information
is
received
by
the Fund.
Distributions
to
shareholders
are
recorded
on
the
ex-dividend
date.
Distributions
from
realized
capital
gains
and
other
distributions,
if
any,
are
recorded
on
the
ex-dividend
date.
Distributable
earnings are
determined
according
to
income
tax
regulations
(tax
basis)
and
may
differ
from
earnings recorded
in
accordance
with
U.S.
GAAP.
These
differences
may
be
permanent
or
temporary.
Permanent differences
are
reclassified
among
capital
accounts
to
reflect
their
tax
character.
These reclassifications
have
no
impact
on
net
assets
or
the
results
of
operations.
Temporary
differences are
not
reclassified,
as
they
may
reverse
in
subsequent
periods.
Realized
and
unrealized
gains
and
losses
and
net
investment
income,
excluding
class
specific
expenses,
are
allocated
daily
to
each
class
of
shares
based
upon
the
relative
proportion
of
net
assets
of
each
class.
Differences
in
per
share
distributions
by
class
are
generally
due
to
differences
in
class
specific
expenses.
f.
Accounting
Estimates
The
preparation
of
financial
statements
in
accordance
with
U.S.
GAAP
requires
management
to
make
estimates
and
assumptions
that
affect
the
reported
amounts
of
assets
and
liabilities
at
the
date
of
the
financial
statements
and
the
amounts
of
income
and
expenses
during
the
reporting
period.
Actual
results
could
differ
from
those
estimates.
g.
Guarantees
and
Indemnifications
Under
the Fund's
organizational
documents,
its
officers
and trustees
are
indemnified
by
the
Fund against
certain
liabilities
arising
out
of
the
performance
of
their
duties
to
the
Fund.
Additionally,
in
the
normal
course
of
business,
the
Fund
enters
into
contracts
with
service
providers
that
contain
general
indemnification
clauses.
The Fund's
maximum
exposure
under
these
arrangements
is
unknown
as
this
would
involve
future
claims
that
may
be
made
against
the Fund
that
have
not
yet
occurred.
Currently,
the Fund
expects
the
risk
of
loss
to
be
remote.

the
monthly
base
fee
plus
or
minus
a
performance
adjustment
for
the
month.
The
performance
adjustment
is
determined
based
on
performance
over
the
thirty-six
month
period
then
ended.
Each
month,
the
performance
adjustment
is
calculated
by
multiplying
the
performance
adjustment
rate
and
the
Fund's
average
net
assets
over
the
performance
period
and
dividing
the
result
by
twelve.
The
resulting
dollar
amount
is
added
to,
or
subtracted
from
the
base
fee
for
that
month.
The
performance
adjustment
rate
is
equal
to
0.03
multiplied
by
the
difference
between
the
Fund's
annualized
performance
(measured
by
the
Fund's
class
A
shares)
and
the
annualized
performance
of
the
S&P
500
Index
each
measured
over
the
performance
period.
The
maximum
annualized
performance
adjustment
rate
is
+/-
0.12%.
The
monthly
base
fee
is
determined
based
on
the
Fund's
average
net
assets
for
the
month,
while
the
performance
adjustment
is
determined
based
on
the
Fund's
average
net
assets
over
the
thirty-six
month
performance
period.
This
means
it
is
possible
that,
if
the
Fund
underperforms
significantly
over
the
performance
period,
and
the
Fund's
assets
have
declined
significantly
over
that
period,
the
negative
performance
adjustment
may
exceed
the
base
fee.
In
this
event,
Putnam
Management
would
make
a
payment
to
the
Fund.
Because
the
performance
adjustment
is
based
on
the
Fund's
performance
relative
to
its
applicable
benchmark
index,
and
not
its
absolute
performance,
the
performance
adjustment
could
increase
Putnam
Management's
fee
even
if
the
Fund's
shares
lose
value
during
the
performance
period
provided
that
the
Fund
outperformed
its
benchmark
index,
and
could
decrease
Putnam
Management's
fee
even
if
the
Fund's
shares
increase
in
value
during
the
performance
period
provided
that
the
Fund
underperformed
its
benchmark
index.
For
the
reporting
period,
the
management
fee
represented
an
effective
rate
(excluding
the
impact
of
any
expense
waiver
in
effect)
of
0.433%
of
the
Fund's
average
net
assets,
which
included
an
effective
base
fee
of
0.530%
and
a
decrease
of
0.097%
($3,187,320)
based
on
performance.
Putnam
Management
retained
Advisers
as
subadvisor
for
the
Fund.
Pursuant
to
the
agreement,
Advisers
provides
certain
advisory
and
related
services
to
the
Fund.
Putnam
Management
pays
a
monthly
fee
to
Advisers
based
on
the
costs
of
Advisers
in
providing
these
services
to
the
Fund,
which
may
include
a
mark-up
not
to
exceed
15%
over
such
costs.
Under
a
subadvisory
agreement,
FTIML
provides
subadvisory
services
to
the
Fund.
The
subadvisory
fee
is
paid by Putnam
Management
based
on
the
average
net
assets
managed
by
FTIML,
and
is
not
an
additional

of

Credit
Facility
Effective

the
Fund,
together
with
other
U.S.
registered
and
foreign
investment
funds
(collectively,
Borrowers)
managed
by
Franklin
Templeton,
are
borrowers
in
a
joint
syndicated
senior
unsecured
credit
facility
totaling
$2.995
billion
(Global
Credit
Facility)
which
matured
on
January
30,
2026.
This
Global
Credit
Facility
provides
a
source
of
funds
to
the
Borrowers
for
temporary
and
emergency
purposes,
including
the
ability
to
meet
future
unanticipated
or
unusually
large
redemption
requests.
Effective
January
30,
2026,
the
Borrowers
renewed
the
Global
Credit
Facility
for
a
one-year
term,
maturing
January
29,
2027,
for
a
total
of
$2.995
billion.
Under
the
terms
of
the
Global
Credit
Facility,
the
Fund
shall,
in
addition
to
interest
charged
on
any
borrowings
made
by
the
Fund
and
other
costs
incurred
by
the
Fund,
pay its
share
of
fees
and
expenses
incurred
in
connection
with
the
implementation
and
maintenance
of
the
Global
Credit
Facility,
based
upon its
relative
share
of
the
aggregate
net
assets
of
all
of
the
Borrowers,
including
an
annual
commitment
fee
of
0.15%
based
upon
the
unused
portion
of
the
Global
Credit
Facility.
These
fees
are
reflected
in
other
expenses
in
the
Statement
of
Operations.
During
the
reporting
period,
the
Fund
did
not
use
the
Global

Borrowings
may
have
been
made
for
temporary
or
emergency
purposes,
including
the
funding
of
shareholder
redemption
requests
and
trade
settlements.
Interest
was
charged

A
closing
fee
equal

the
committed
line
of
credit
and
0.04%
of
the

of
credit
was
paid
by
the
participating

and
a
$75,000
fee
was
paid
by
the
participating
funds
to
State
Street
as

Fair
Value
Measurements
The
Fund
follows
a
fair
value
hierarchy
that
distinguishes
between
market
data
obtained
from
independent
sources
(observable
inputs)
and
the Fund's
own
market
assumptions
(unobservable
inputs).
These
inputs
are
used
in
determining
the
value
of
the
Fund's financial
instruments
and
are
summarized
in
the
following
fair
value
hierarchy:
Level
1
-
quoted
prices
in
active
markets
for
identical
financial
instruments
Level
2
-
other
significant
observable
inputs
(including
quoted
prices
for
similar
financial
instruments,
interest
rates,
prepayment
speed,
credit
risk,
etc.)
Level
3
-
significant
unobservable
inputs
(including
the
Fund's
own
assumptions
in
determining
the
fair
value
of
financial
instruments)
The
input
levels
are
not
necessarily
an
indication
of
the
risk
or
liquidity
associated
with
financial
instruments
at
that
level.
A
summary
of
inputs
used
as
of
December
31,
2025,
in
valuing
the
Fund's assets
and
liabilities carried
at
fair
value,
is
as
